Product details
Overview
MIC2202BMM-TR from Micrel is a high-efficiency, 2MHz synchronous buck DC-DC converter with internal MOSFETs, supporting 2.3V–5.5V input and adjustable output down to 0.5V at up to 600mA. It achieves >95% efficiency with only four external components, stable operation using a 1µF ceramic output capacitor, and ultra-fast transient response (500kHz gain bandwidth), making it ideal for powering CPU cores and RF circuitry in cellular phones and PDAs.
For engineers reviewing the MIC2202BMM-TR datasheet, MIC2202BMM-TR pinout, MIC2202BMM-TR application, or MIC2202BMM-TR equivalent, key selection considerations include its 2MHz fixed-frequency PWM control, SYNC_IN/SYNC_OUT daisy-chain capability, internal compensation, 10-pin MSOP package, and compatibility with all-ceramic passive networks for compact, low-noise power delivery in space-constrained portable electronics.
Technical Context
The MIC2202BMM-TR implements voltage-mode PWM control with a proprietary internal ramp generator and error amplifier referenced to a precise 0.5V feedback threshold. Its 2MHz oscillator operates across –40°C to +125°C, enabling predictable EMI behavior and harmonic filtering in RF-sensitive systems.
It integrates a P-channel high-side and N-channel low-side MOSFET pair with typical RDS(ON) of 0.55Ω/0.75Ω (at VFB = 0.55V), supports external synchronization from 1.6MHz to 2.5MHz, and features a dedicated BIAS pin (2.3V ±0.12V) requiring a 10nF bypass capacitor for internal bias stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.3V to 5.5V - supports single-cell Li-ion, Li-poly, and regulated 3.3V/5V rails without pre-regulation. |
| Output Voltage Range | Adjustable from 0.5V to VIN - enables direct core supply for modern low-voltage processors and RF ICs. |
| Max Output Current | 600mA continuous - sufficient for baseband processors, RF power amps, and FPGA I/O banks. |
| Switching Frequency | 2MHz (±10%) - allows use of tiny 2.2µH inductors and 1µF ceramic capacitors, minimizing board area. |
| Feedback Reference | 0.500V ±1.25% - enables accurate output regulation with standard resistor divider tolerances. |
| Quiescent Current | ≤1µA in shutdown - preserves battery life during system sleep modes. |
| Thermal Protection | Over-temperature shutdown at 160°C with 20°C hysteresis - prevents thermal runaway under sustained overload. |
Pinout & Package
Package: 10-pin MSOP (3mm × 4.9mm, 0.5mm pitch), exposed pad (EP) connected to GND for thermal enhancement. θJA = 115°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SW) | Switch Node | Drives external inductor; connects internally to source of high-side P-MOSFET and drain of low-side N-MOSFET. |
| 2 (VIN) | Input Supply | Primary power input; requires ≥1µF ceramic bypass to GND close to pin. |
| 3 (SYNC_IN) | External Sync Input | Accepts 1.6–2.5MHz clock signal to override internal oscillator; logic-high threshold 0.9V typical. |
| 4 (SYNC_OUT) | Sync Output | Open-collector output mirroring internal oscillator frequency; requires external 10kΩ pull-up for master-slave chaining. |
| 5 (EN) | Enable Control | Active-high logic input; 0.9V typical turn-on threshold with 20mV hysteresis for noise immunity. |
| 6 (FB) | Feedback Input | Connects to resistor divider; compares output voltage against 0.5V reference to regulate VOUT. |
| 7 (BIAS) | Internal Bias Supply | 2.3V linear regulator output; must be bypassed with 10nF ceramic to GND-no external load permitted. |
| 8,9,10 (GND) | Ground Terminals | Three dedicated GND pins plus EP (backside pad) - minimize ground impedance and improve thermal dissipation. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62231DRVR | 2.25MHz fixed frequency, 0.6V reference, 650mA IOUT, 2.05–6.0V input, 6-pin WSON package. | Lacks SYNC_IN/SYNC_OUT and BIAS pin; no daisy-chain support; smaller package but higher thermal resistance (θJA = 170°C/W). | Preferred when board space is critical and multi-regulator synchronization is unnecessary. |

FAQ
What is the minimum output capacitor value supported by the MIC2202BMM-TR?
The MIC2202BMM-TR is explicitly characterized and guaranteed stable with a 1µF ceramic output capacitor (X5R or X7R dielectric). Using smaller values risks instability or poor transient response. Larger values up to 15µF are acceptable but require feed-forward capacitance if exceeding 15µF to prevent startup current-limit triggering.
Does the MIC2202BMM-TR support adjustable output voltage, and how is it set?
Yes, the MIC2202BMM-TR is an adjustable-output regulator. Output voltage is set via a resistor divider from VOUT to FB, referenced to the internal 0.5V feedback threshold. For example, a 10kΩ (R1) and 1.78kΩ (R2) divider yields 3.3V: VOUT = 0.5V × (1 + R1/R2). The MIC2202BMM-TR datasheet provides full calculation guidance and layout recommendations.
Can multiple MIC2202BMM-TR devices be synchronized, and how?
Yes, the MIC2202BMM-TR supports master-slave synchronization via its SYNC_IN and SYNC_OUT pins. Connect the SYNC_OUT (open-collector) of one device-with a 10kΩ pull-up-to the SYNC_IN of another. This daisy-chain configuration locks all devices to the same switching frequency and phase, reducing beat frequencies and simplifying EMI mitigation in multi-rail systems.
What is the purpose of the BIAS pin on the MIC2202BMM-TR, and how must it be used?
The BIAS pin on the MIC2202BMM-TR provides a dedicated 2.3V internal bias supply for the control circuitry. It must be bypassed to GND with a 10nF ceramic capacitor-no external load is permitted. Using BIAS as a general-purpose supply or omitting the capacitor causes regulation failure and potential oscillation due to internal supply noise coupling.
What protection features does the MIC2202BMM-TR include?
The MIC2202BMM-TR integrates thermal shutdown (160°C trip, 20°C hysteresis), cycle-by-cycle current limiting (1.0–2.5A), and logic-controlled micropower shutdown (<1µA quiescent current). It also features built-in undervoltage lockout on EN and overvoltage clamping on SYNC_IN/VIN pins per absolute maximum ratings-ensuring robust operation under fault conditions.
