LMZ36002RVQR Visão geral
A power module is a complete integrated power solution that combines the switching controller, MOSFETs, inductor, and critical passives inside a single package, eliminating the most error-prone parts of discrete buck converter design. Power modules belong to the broader category of switching regulators (buck converters) within the DC/DC converter family, which itself sits in the power management IC hierarchy. Compared to discrete buck designs, modules reduce radiated EMI, shorten time-to-market, and free the engineer from inductor selection and feedback compensation.
Key features include 4.5V to 60V wide input range suitable for 12V, 24V, and 48V industrial buses, 2A continuous output current, adjustable switching frequency, external synchronization, internal MOSFETs with current-mode control, integrated bootstrap, and built-in protection including thermal shutdown, input undervoltage lockout, and cycle-by-cycle current limit. The LMZ36002RVQR requires as few as three external components (input cap, output cap, feedback resistors) to deliver a working regulated supply.
Internally the LMZ36002 uses peak current-mode control with internal compensation, a high-side P-channel / low-side N-channel MOSFET pair, and a coupled shielded inductor that minimizes radiated EMI. The exposed thermal pad on the QFN package provides a low thermal resistance path, allowing the module to deliver full 2A output across industrial temperature ranges without external heatsinking under most conditions.
Typical applications include factory automation 24V point-of-load rails, industrial sensor and actuator power, building automation, battery-powered systems up to 60V, and PoL supplies for FPGA / DSP / MCU subsystems. The wide input range also suits telecom equipment operating from nominal 48V backplanes.
When designing with this device, prioritize a 4-layer PCB with a continuous ground pour and stitch vias beneath the exposed thermal pad to keep the junction temperature within safe limits under full load. The RT/SS pin sets soft-start and switching frequency — refer to the manufacturer datasheet for resistor and capacitor selection tables before finalizing the BOM.

Aplicações típicas
LMZ36002RVQR é adequado para 6 aplicaçãos: Industrial 24V Point-of-Load Rails, Building Automation and HVAC Control, Telecom 48V Backplane Subsystems, Battery-Powered Systems up to 60V, FPGA and DSP Point-of-Load Power, Automotive Auxiliary and Industrial Sensor Power.
Industrial 24V Point-of-Load Rails
The LMZ36002RVQR fits 24V industrial PoL rails because its 4.5V to 60V input window tolerates the 18V to 36V swing on nominal 24V factory buses without a pre-regulator. The integrated shielded inductor and 2A continuous output deliver clean 3.3V, 5V, or 7.5V rails for PLC I/O modules, sensor front-ends, and motor-driver logic. The module's peak current-mode control and 200 kHz to 1 MHz switching range allow designers to move the fundamental away from sensitive analog frequencies, while the 43-pin B3QFN package keeps the design footprint small inside DIN-rail enclosures.
Recomendado
Building Automation and HVAC Control
Building automation controllers operate from 24V AC/DC rectified rails with significant ripple and transient swings, so the LMZ36002RVQR's wide 4.5V to 60V input accommodates rectified 24VAC outputs directly. Its 2A output powers microcontroller, wireless communication, and relay-driver subsystems in HVAC controllers, thermostats, and access-control panels. The integrated module eliminates manual inductor selection, which is critical for design houses that need a single BOM across multiple SKUs. The exposed thermal pad distributes heat uniformly across the PCB, enabling fanless operation in wall-mounted enclosures.
Recomendado
Telecom 48V Backplane Subsystems
Nominal 48V telecom backplanes require point-of-load converters that survive transient excursions above 60V, and the LMZ36002RVQR's 60V absolute-max rating provides margin against load-dump and hot-swap transients on the backplane. The 2A output powers DSP, FPGA housekeeping, and line-interface cards that share a common -48V return. The adjustable switching frequency and external synchronization allow the LMZ36002RVQR to lock to a master clock, eliminating beat frequencies between converter stages in the same chassis. Built-in UVLO prevents backfeeding during upstream power sequencing.
Recomendado
Battery-Powered Systems up to 60V
Battery stacks from 12V lead-acid through 48V lithium chemistries fit directly into the LMZ36002RVQR's 4.5V to 60V input window, making it ideal for e-mobility controllers, portable instrumentation, and backup-power systems. The 2A output powers downstream regulators, motor pre-drivers, and communication modules from the same battery stack. Adjustable soft-start through the RT/SS pin limits inrush from discharged battery packs, protecting both the module and the upstream fuse. The shielded internal inductor keeps radiated EMI low, which matters in portable enclosures without metal shielding.
Recomendado
FPGA and DSP Point-of-Load Power
FPGA and DSP subsystems require low-noise, high-current point-of-load rails near the load to minimize IR drop and switching-node ringing, and the LMZ36002RVQR's 2A output supplies core and auxiliary rails from a 12V or 24V intermediate bus. Peak current-mode control provides a fast transient response that tracks DSP load steps within microseconds. The module's exposed thermal pad can be soldered directly to an inner PCB ground plane for low thermal resistance, and the integrated shielded inductor eliminates one of the largest discrete EMI sources. Adjustable switching lets the designer avoid interference with sensitive PLL frequencies.
Recomendado
Automotive Auxiliary and Industrial Sensor Power
In automotive auxiliary systems and industrial sensor hubs, the LMZ36002RVQR's 60V input rating handles load-dump transients on 12V and 24V automotive rails while delivering 2A for sensor clusters, CAN transceivers, and microcontroller subsystems. For AEC-Q100 qualified applications, the LMZ36002RVQR must be replaced by an automotive-grade equivalent; otherwise the standard part is widely used in non-safety automotive subsystems. The integrated module reduces PCB area versus discrete buck designs, which matters in space-constrained ECU modules and sensor pods. Built-in protection covers thermal shutdown and cycle-by-cycle current limit.

Notas de projeto
Estimated: at VIN = 24V, VOUT = 5V, IOUT = 2A, the LMZ36002RVQR dissipates roughly (24V - 5V) × 2A = 38W internally. The 43-pin B3QFN module's exposed thermal pad must be soldered to a continuous copper pour of at least 1 square inch on inner and outer PCB layers with thermal vias to keep junction temperature within the 105 C operating limit. Without adequate PCB copper, the module will thermally limit below the rated 2A output in high-VIN designs.
Place the input ceramic capacitors (10 uF X7R minimum) directly on the VIN/PGND pads within 5 mm of the package to minimize switching-loop inductance. Place the output ceramic capacitors (22 uF X7R minimum, low-ESR) directly on the VOUT/PGND pads. Avoid routing analog signal traces under the module's switching node to prevent injected ripple on sensitive analog grounds.
Do not exceed the absolute maximum VIN of 65V even for transients; add a TVS diode or upstream fuse on the 48V telecom rail. The RT/SS pin sets both switching frequency and soft-start - using the wrong resistor value causes either thermal runaway or excessive inrush. The exposed pad (pin 43) MUST be soldered; floating the thermal pad triggers thermal shutdown within seconds of full load.
Use a 4-layer PCB with the inner layers dedicated to a continuous ground pour stitched with vias around the module's PGND pins. Keep the high-di/dt switching loop (VIN - HS MOSFET - inductor - PGND) as tight as possible; this loop's area directly determines radiated EMI. Reference the LMZ36002 manufacturer datasheet evaluation board layout for a known-good reference that passes CISPR 22 EMI without external shielding.
