MIC23150-GYMT-TR Overview
A synchronous buck regulator is a type of DC-DC switching converter that steps a higher input voltage down to a lower output voltage using a high-side and a low-side (synchronous rectifier) MOSFET integrated on the die, replacing the external Schottky diode of a conventional buck converter to improve efficiency. Within the power management hierarchy - power management IC, switching regulator, buck converter - the MIC23150 targets battery-powered and space-constrained point-of-load applications.
Key differentiating features include the proprietary HyperLight Load mode, which combines 4MHz PWM operation in continuous conduction with ultra-fast transient response and very high light-load efficiency; peak efficiency of 93% in continuous conduction mode; and support for a very small 0.47uH inductor with an output capacitor as small as 2.2uF, enabling a complete solution under 1mm height. The 4MHz switching frequency moves noise far above sensitive RF and audio bands and shrinks the magnetics to tiny chip inductors.
Architecturally, the device integrates both power MOSFETs, the 4MHz oscillator, and the HyperLight Load control loop, which automatically transitions between PWM and ultra-light-load operation to keep output ripple very low across the entire load range. This makes it well suited to powering processor core rails that swing from sleep-level microamp loads to full 2A bursts with minimal droop.
Typical applications include supplying processor and SoC core voltages, point-of-load rails in portable and battery-powered devices, RF module power supplies in cellular and IoT terminals, and embedded power management in space-limited industrial designs. The 2.7V-5.5V input range directly accepts single-cell Li-ion batteries and 5V rails.
Design consideration: at 4MHz, layout discipline is critical - keep the input capacitor, inductor, and SW node loop as small as possible, and select a low-DCR 0.47uH inductor rated above 2A to preserve efficiency and transient performance.

Typical Applications
MIC23150-GYMT-TR is suitable for 6 applications: Processor Core Voltage Supply, Battery-Powered Portable Devices, RF and Wireless Module Power, Point-of-Load Rails in Embedded Systems, Space-Constrained Consumer Electronics, IoT Sensor Nodes and Smart Home Devices.
Processor Core Voltage Supply
The MIC23150-GYMT-TR is explicitly designed by Microchip for supplying processor core voltages: HyperLight Load mode delivers ultra-fast transient response so the 1.8V rail recovers quickly when the processor wakes from sleep and steps from microamps to multi-hundred-milliamp bursts. The 23uA quiescent current keeps standby drain negligible in battery-powered systems, and 93% peak efficiency at 4MHz minimizes heat in dense layouts. With a 0.47uH inductor and 2.2uF output capacitor, the entire point-of-load solution fits in under 1mm of height directly adjacent to the SoC, shortening the high-di/dt loop. Place the converter on the same PCB layer as the core with a solid ground plane to control switching noise at 4MHz.

Battery-Powered Portable Devices
In portable and wearable products, the MIC23150-GYMT-TR accepts a single-cell Li-ion battery directly (2.7V-5.5V input covers 3.0V-4.2V cell voltage plus dropout headroom), producing a regulated 1.8V rail at up to 2A. The 23uA quiescent current and HyperLight Load light-load operation preserve battery life during standby, while 93% peak efficiency extends runtime during active use. The 2x2mm TDFN-8 package with a 0.47uH chip inductor occupies minimal board area - critical in earbuds, smartwatch, and tracker form factors - and the sub-1mm total solution height fits thin industrial designs. The 4MHz switching frequency keeps switching ripple far from audio-band circuitry.
Recommended
RF and Wireless Module Power
Cellular, IoT, and RF transmitter modules draw burst currents from microamps in idle to amperes during transmit slots. The MIC23150-GYMT-TR handles these load steps with ultra-fast transient response and very low output ripple across the whole load range, per the Microchip datasheet, protecting the module's 1.8V supply from droop-induced transmit errors. The 4MHz switching frequency places switching harmonics well above typical IF and baseband bands, easing filtering. Place the converter close to the module with a 2.2uF or larger ceramic output capacitor and a compact input loop; verify conducted emissions against your radio regulatory profile when integrating near sensitive receivers.

Point-of-Load Rails in Embedded Systems
Embedded controllers and FPGAs commonly need multiple low-voltage rails derived from a 5V backplane or industrial supply. The MIC23150-GYMT-TR generates a local 1.8V I/O or auxiliary rail at up to 2A from the 5V rail, freeing the main power tree from long low-voltage distribution traces. Its small 2x2mm footprint lets designers place regulation exactly at the load, improving transient performance and reducing copper losses. The 4MHz operation shrinks magnetics so several converters fit in the space of one low-frequency regulator. Ensure the 5V source stays within the 2.7V-5.5V envelope and add bulk capacitance upstream for inrush and cable-inductance transients.
Recommended
Space-Constrained Consumer Electronics
Consumer products such as set-top boxes, smart speakers, displays, and small appliances need dense, low-cost power conversion. The MIC23150-GYMT-TR provides a fixed 1.8V 2A rail from a 5V input with a component count of one inductor plus two small ceramic capacitors, reducing BOM cost and placement time. The 4MHz HyperLight Load architecture holds output ripple very low throughout the load range, which matters for audio and video subsystems sharing the rail. The GREEN MLF-8 RoHS-compliant package supports lead-free reflow assembly, and the sub-1mm height suits thin enclosures and stacked-board assemblies where every tenth of a millimeter counts.
Recommended
IoT Sensor Nodes and Smart Home Devices
Battery- or USB-powered IoT nodes benefit from the MIC23150-GYMT-TR's combination of 23uA quiescent current, high light-load efficiency, and a tiny 2x2mm footprint. A 5V USB input or Li-ion cell converts to a 1.8V rail powering MCU cores, radios, and sensors. During duty-cycled sleep periods, HyperLight Load mode keeps conversion efficient at microamp loads rather than dropping into lossy discontinuous operation, directly extending battery life in years-long deployments. The 0.47uH inductor and 2.2uF output capacitor keep the solution small enough for coin-cell-adjacent layouts, and the fast transient response cleanly powers radio transmit bursts without resetting the MCU.

Key Differentiators
- Sub-1mm complete solution height (vs MIC23150-CYMT-TR)
- 23uA quiescent current with HyperLight Load (vs Conventional low-frequency buck converters (e.g., typical 1-2MHz, 100uA-class regulators))
- 4MHz operation shrinks magnetics (vs Lower-frequency (1-2MHz) 2A buck regulators)
- Trade-off: fixed 1.8V output only (vs MIC23150-CYMT-TR (1.0V) and adjustable-output buck regulators)
Design Notes
At 4MHz switching frequency, layout dominates performance. Keep the loop from the input capacitor through PVIN, the SW node, and PGND as short and tight as possible; use a solid, unbroken ground plane under the 2x2mm TDFN-8 and connect the exposed thermal pad to ground with multiple vias for heat spreading and low inductance. Place the 0.47uH inductor directly adjacent to the SW pin and route the feedback trace away from SW to avoid coupling switching edges into the control loop. A minimal SW-node area also limits radiated emissions at 4MHz and its harmonics.
Select the 0.47uH inductor for saturation current comfortably above the 2A peak load and low DCR to protect the 93% peak efficiency figure; a core that saturates near full load causes abrupt efficiency loss and current-limit misbehavior. Use X5R/X7R ceramic capacitors: 2.2uF minimum output and a low-ESR input capacitor placed close to PVIN. Remember that effective capacitance drops with DC bias - a 2.2uF 0603 at 1.8V bias may deliver only ~1.4uF, so upsize voltage rating or value if transient response degrades.
Do not exceed the 5.5V maximum input - USB VBUS transients and unregulated adapter outputs can exceed this, so add local input protection (TVS or clamp) on raw barrel-jack or automotive-adjacent inputs. Confirm the output-voltage letter code when purchasing: G = 1.8V, C = 1.0V; ordering the wrong suffix yields a working regulator at the wrong rail with no error indication. For battery applications, verify the cell's low-battery cutoff stays at or above 2.7V to remain within the MIC23150 operating range.
