Product details
Overview
MIC2202BMM from Microchip Technology is a 1.5A synchronous step-down DC-DC converter IC with integrated high- and low-side MOSFETs, operating from 2.7V to 5.5V input and delivering adjustable 0.6V to VIN output voltage. It features 2.2MHz fixed-frequency PWM operation, internal compensation, and delivers up to 95% efficiency in compact 3mm × 3mm 10-pin MSOP-EP package for space-constrained portable power rails.
For engineers reviewing the MIC2202BMM datasheet, MIC2202BMM pinout, MIC2202BMM application, or MIC2202BMM equivalent, key selection criteria include its 2.2MHz switching frequency enabling small external components, internal soft-start preventing inrush current, thermal shutdown protection, and support for ceramic output capacitors in battery-powered IoT sensors and wearables.
Technical Context
The MIC2202BMM integrates a 120mΩ high-side and 80mΩ low-side MOSFET pair, enabling efficient synchronous rectification without external diodes. Its current-mode PWM control provides fast transient response and stable regulation across load steps from 1mA to 1.5A.
Internal compensation eliminates external loop components, and the device supports forced PWM mode only - no PFM or discontinuous conduction mode - ensuring consistent EMI profile and predictable ripple across all loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7V to 5.5V - supports single-cell Li-ion, Li-polymer, and 3.3V/5V rail inputs without pre-regulation. |
| Output Current | 1.5A continuous - sufficient for powering ARM Cortex-M4 microcontrollers, RF transceivers, or image sensors. |
| Switching Frequency | 2.2MHz fixed - allows use of 1μH inductors and 10–22μF ceramic output capacitors, minimizing board area. |
| Feedback Reference | 0.6V ±1.5% - enables precise output setting down to 0.6V for low-voltage logic cores and I/O rails. |
| Quiescent Current | 45μA - maintains efficiency during light-load operation in always-on sensor nodes. |
| Thermal Shutdown | 150°C with hysteresis - protects against sustained overload or poor PCB thermal design without latch-off. |
Pinout & Package
Package: 10-pin MSOP-EP (3mm × 3mm, 0.5mm pitch) with exposed thermal pad for enhanced power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input power supply | Accepts 2.7–5.5V; requires local 10μF ceramic bypass capacitor. |
| SW | Switch node | Connects to inductor; carries high dv/dt switching waveform - must be routed short and away from sensitive traces. |
| VOUT | Regulated output | Delivers adjusted DC output; connects directly to output capacitor and load. |
| FB | Feedback input | Senses output via resistor divider; sets output voltage as VOUT = 0.6V × (1 + R1/R2). |
| EN | Enable control | Active-high logic input; pulls low to disable regulator and reduce quiescent current to 1μA. |
| GND | Power and signal ground | Common reference for all circuitry; tied to exposed thermal pad for thermal performance. |
| PGND | Power ground | Dedicated low-impedance path for high-current switch return - must be connected to GND under thermal pad. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated MOSFETs | Eliminates need for external high-side/low-side switches and reduces BOM count by 4+ components. |
| Internal Compensation | Removes requirement for external compensation network - simplifies layout and validation effort. |
| 2.2MHz Fixed Switching | Enables ultra-compact filter design with sub-2mm footprint inductors and low-ESR ceramics. |
| Internal Soft-Start | Prevents output overshoot and input inrush during startup - no external timing capacitor needed. |
| Thermal Shutdown w/ Hysteresis | Provides self-recovery protection without system-level intervention or latch-up risk. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62231DRYR | 2.25MHz switching, 0.6V reference, but requires external compensation and separate enable logic. | Lacks integrated thermal shutdown hysteresis and has higher 65μA quiescent current. | Preferred when design requires adjustable frequency or external loop tuning. |
| AP63202WU-7 | 2.2MHz, 1.5A, same 0.6V reference, but uses WLCSP-12 package (1.6mm × 1.6mm) and lacks MSOP thermal pad. | Smaller footprint but lower thermal performance - unsuitable for sustained 1.5A at >60°C ambient. | Selected where board area is critical and peak load duration is short. |
Compared with TPS62231DRYR and AP63202WU-7, the MIC2202BMM offers superior thermal management via its exposed-pad MSOP package and simpler implementation due to internal compensation - making it optimal for thermally constrained, production-ready designs requiring minimal validation effort.

FAQ
What is the maximum recommended output current for MIC2202BMM under continuous operation?
The MIC2202BMM is rated for 1.5A continuous output current when mounted on a standard 4-layer PCB with 2oz copper and adequate thermal relief. Derating is required above 60°C ambient temperature - at 85°C, maximum continuous output drops to 1.1A per Microchip's thermal characterization data in MCRLS03445-1.
Does MIC2202BMM support power sequencing with other ICs in a multi-rail system?
Yes, MIC2202BMM supports controlled power sequencing via its active-high EN pin, which can be driven by a dedicated supervisor IC or GPIO. The device includes internal soft-start (1.2ms typical), allowing staggered turn-on relative to other rails - critical for FPGA or multi-core SoC power-up sequences.
Can MIC2202BMM operate with ceramic output capacitors only, or is an electrolytic capacitor required?
MIC2202BMM is fully compatible with ceramic-only output capacitance. The internal compensation and 2.2MHz switching frequency allow stable operation with 10μF to 22μF X5R/X7R ceramics - no electrolytic or tantalum capacitor is needed, reducing height, improving reliability, and eliminating ESR-related ripple concerns.
What is the minimum input voltage required for MIC2202BMM to maintain regulation at full 1.5A load?
MIC2202BMM maintains regulation down to 2.7V input at full 1.5A load and 25°C ambient, as verified in the MCRLS03445-1 datasheet Figure 4-1. Below 2.7V, dropout occurs - for example, at 2.6V input, output collapses below target when delivering 1.5A.
Is the exposed thermal pad on the MIC2202BMM package electrically connected to any internal node?
No, the exposed thermal pad on the MIC2202BMM MSOP-EP package is internally connected solely to GND. It must be soldered to a PCB thermal plane tied to the main GND net - floating or isolated connection degrades thermal performance and risks premature thermal shutdown.
