MC34708VMR2 - PMIC for i.MX50/53, 6 Buck, 8 LDO | NXP
MPN： MC34708VMR2 ✗ 停產MC34708VMR2 概覽
A power management IC (PMIC) is a specialized voltage regulator subsystem that integrates multiple DC-DC converters and linear regulators onto a single die, providing all processor rails - core, memory, and peripherals - with correct sequencing and coordination. In the power-management hierarchy, the MC34708 sits between a single-input supply and the multi-rail demands of an applications processor, replacing a discrete multi-chip power tree.
Key features include six multi-mode buck regulators that supply the processor core, memory, and peripherals directly, eight low-dropout regulators for analog and I/O rails, and an integrated 10-bit ADC that enables battery voltage and general-purpose analog monitoring. This level of integration reduces board area, simplifies power-up sequencing, and ensures the rail timing required by i.MX50/i.MX53 boot behavior.
Architecturally, the bucks support multi-mode operation (PWM/PFM), allowing high efficiency at heavy load and low quiescent consumption at light load, while the LDOs provide low-noise rails for analog domains. The single 1.8 V to 4.5 V input suits single-cell Li-ion or Li-MnO2 battery applications as well as 3.3 V wall-adapters.
Typical applications include i.MX50/i.MX53 tablet and e-reader designs, industrial HMI terminals, and embedded Linux systems requiring a complete, processor-matched power tree. Note that NXP recommends the MMPF0100 or MC34709 for new designs, as i.MX50/i.MX53 are mature processors.
Design consideration: verify buck output-current allocation against your processor core frequency, and confirm the specific programming/configuration variant of the MC34708 device, since rail voltages are preset per part number suffix.

典型應用
MC34708VMR2 適用於 6 應用s: i.MX50 / i.MX53 Tablet and E-Reader Power, Industrial HMI and Embedded Linux Terminals, Battery-Powered Portable Instrumentation, Medical Monitoring Devices, Networking and Gateway Equipment, Smart Home and IoT Hub Controllers.
i.MX50 / i.MX53 Tablet and E-Reader Power
The MC34708VMR2 is purpose-built for i.MX50 and i.MX53 tablet and e-reader platforms, where a single 1.8 V to 4.5 V Li-ion input must generate the processor core, DDR memory, and peripheral rails with correct sequencing. Its six multi-mode bucks deliver the core and memory rails with PWM/PFM operation that maintains efficiency across the wide load range of multimedia playback versus standby, while the eight LDOs supply low-noise analog domains such as audio codec and display bias. The integrated 10-bit ADC monitors battery voltage for fuel-gauging and low-battery shutdown. Because rail voltages and boot sequencing are factory-set for i.MX50/53, board bring-up time is reduced compared with a discrete power tree, and total PMIC board area is limited to the 13x13 mm BGA footprint.

Industrial HMI and Embedded Linux Terminals
Industrial human-machine interface terminals based on i.MX53 benefit from the MC34708VMR2's integrated power tree: the six bucks supply the ARM core, DDR memory, and I/O rails, and the eight LDOs power Ethernet PHY, touch controller, and display analog rails from one 3.3 V or battery input within the 1.8 V to 4.5 V range. The 10-bit ADC supports monitoring of supply health for predictive maintenance logging. The 206-ball MAPBGA (13x13 mm) package consolidates what would otherwise be a dozen discrete regulators, improving reliability in vibration-prone factory environments by reducing solder-joint count. Designers should verify industrial ambient temperature against the datasheet rating and allocate buck output currents to core-frequency operating points before finalizing the layout.

Battery-Powered Portable Instrumentation
Portable instruments and data loggers built around i.MX50/i.MX53 processors use the MC34708VMR2 to derive all processor rails directly from a single-cell Li-ion cell, exploiting the full 1.8 V to 4.5 V input span down to deep battery discharge. Multi-mode buck regulation keeps light-load quiescent consumption low during sleep states, extending run time, while PWM mode preserves efficiency during active measurement and display updates. The 10-bit ADC can be repurposed to monitor battery voltage or external sensor inputs, replacing a separate monitoring ADC and saving board area. Because the PMIC was co-developed with the i.MX50/53 power-management firmware, sleep/wake rail sequencing is handled without external sequencer ICs, simplifying low-power state-machine design in battery-critical products.

Medical Monitoring Devices
Medical monitoring equipment using i.MX53 graphics capability can employ the MC34708VMR2 to power the processor subsystem from a Li-ion pack or regulated medical-grade 3.3 V/5 V rail within the 1.8 V to 4.5 V input window. The eight LDOs provide low-noise supply for analog front-end circuits where ripple would degrade biosignal measurement quality, and the 10-bit ADC permits battery and rail monitoring required by safety logs. Integration of six bucks and eight LDOs in one 13x13 mm 206-ball package reduces component count on densely populated patient-facing boards, aiding cleaning-friendly, sealed mechanical designs. Verify the part's qualification level against your applicable medical risk-management process, since this standard-grade PMIC was originally targeted at consumer tablets rather than medical end-equipment.
推薦
Networking and Gateway Equipment
Compact i.MX53-based gateways and network appliances use the MC34708VMR2 to generate core, DDR, and I/O rails from a common 3.3 V backplane feed inside the 1.8 V to 4.5 V input range. The multi-mode bucks remain efficient across the traffic-dependent load swings typical of networking equipment, and the eight LDOs supply clean analog rails for Ethernet PHYs and management interfaces. The integrated 10-bit ADC can monitor input voltage for brown-out logging in unattended installations. Housing the entire processor power tree in a single 206-ball MAPBGA shortens the power distribution network, reducing rail impedance and decoupling complexity on multi-layer boards, and its deterministic boot sequencing removes the need for a CPLD-based power sequencer that discrete designs typically require.
推薦
Smart Home and IoT Hub Controllers
Smart-home hubs built on i.MX50/i.MX53 leverage the MC34708VMR2 as a processor-matched power solution accepting wall-adapter (3.3 V to 4.5 V) or backup-battery inputs. The six bucks power CPU, LPDDR memory, Wi-Fi/RF module rails, and flash memory with sequencing the i.MX boot ROM expects, while the eight LDOs serve audio, sensor, and RTC domains with low-noise rails. The 10-bit ADC enables backup-battery voltage supervision so the hub can report power events to the cloud before shutdown. The single 13x13 mm BGA footprint frees board area for wireless modules in space-conformed enclosure designs, and consolidating regulation into one IC reduces total quiescent draw in the always-on standby state that IoT hubs spend most of their lifetime in.

設計說明
The MC34708VMR2 is programmed at the factory with specific rail voltages and sequencing for i.MX50/i.MX53 boot requirements. Before layout, obtain the programming specification for your exact device suffix from NXP and confirm each buck output matches your processor's operating-point table (core voltage scales with CPU frequency). Mismatch between preset rail voltages and processor operating points is the most common cause of boot instability on i.MX53 designs. Estimated: allocate each buck's load budget from your processor's worst-case current table, not typical values, since the six bucks share a single 1.8 V to 4.5 V input whose total current equals the sum of all rails divided by per-rail efficiency.
For the 206-ball MAPBGA (13x13 mm), use a via-in-pad or dog-bone fanout with at least a 6-layer stack to route six buck power stages plus eight LDO rails. Place buck input capacitors close to the VIN/PVIN balls and keep high-di/dt buck loops (input cap, high-side switch ball, catch diode/low-side ball, ground) as small as possible to limit EMI. The center thermal balls must connect to a solid ground plane with a via array for heat spreading - estimate the ground vias from total PMIC dissipation, which at Li-ion input and multi-amp core current can reach the watt range.
Do not design new products with the MC34708VMR2 without a lifecycle plan: NXP recommends the MMPF0100 or MC34709 for new designs because i.MX50/i.MX53 are mature processors, so MC34708 availability will tighten. Verify the device's specific PMIC configuration variant (rail voltages differ by part-number suffix), and confirm RoHS/reach certificates with date code from NXP since the reviewed web data did not state compliance explicitly. Sample-stock purchases should be checked for date codes older than five years before assembly.
