Product details
Overview
MIC2876-5.0YMT-T5 from Microchip Technology is a fixed-output, 5.0V synchronous boost regulator with 4.8A switch current capability, 2 MHz switching frequency, and bi-directional true load disconnect. It operates from 2.5V to 5.5V input, delivers up to 95% efficiency, and supports automatic bypass mode when VIN ≥ VOUT - ideal for USB OTG power delivery in portable devices.
For engineers reviewing the MIC2876-5.0YMT-T5 datasheet, MIC2876-5.0YMT-T5 pinout, MIC2876-5.0YMT-T5 application, or MIC2876-5.0YMT-T5 equivalent, key selection considerations include its 8-pin 2 mm × 2 mm UDFN package with exposed thermal pad, <1 µA shutdown current, integrated anti-ringing switch for EMI reduction, and –40°C to +125°C junction temperature range.
Technical Context
The MIC2876-5.0YMT-T5 implements current-mode PWM control with internal 2 MHz oscillator and soft-start circuitry. Its bi-directional load disconnect uses an NMOS/PMOS power stage with back-gate diode isolation, enabling leakage-free shutdown even with as low as 0.3V on IN.
It features pulse-skipping mode at light loads to maintain high efficiency, integrated anti-ringing switch clamping SW to IN during DCM, and automatic transition between boost and bypass modes based on VIN vs. VOUT comparison - all without external compensation components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5V to 5.5V - supports single-cell Li-ion, Li-poly, or USB-powered inputs without pre-regulation. |
| Output Voltage | Fixed 5.0V ±1.5% - eliminates external feedback resistors and ensures stable USB-compliant output. |
| Switch Current Limit | 4.8A typical - enables high-current boost for parallel battery systems or HDMI host supplies. |
| Switching Frequency | 2 MHz (1.6–2.4 MHz) - allows use of compact 1 µH inductors and reduces output ripple without increasing EMI filtering burden. |
| Shutdown Current | <1 µA - extends battery life in always-on portable equipment during standby. |
| Operating Temperature | –40°C to +125°C junction - qualified for industrial and automotive-adjacent portable applications. |
| Package | 8-pin 2 mm × 2 mm UDFN with exposed thermal pad - provides low θJA (90°C/W) and space-efficient layout for thin-profile devices. |
Pinout & Package
Package: 8-pin 2 mm × 2 mm UDFN (MT) with exposed thermal pad (EP), rated for –40°C to +125°C junction temperature and optimized for thermal performance when EP is connected to AGND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 SW | Boost Switch Node | Connects to inductor; carries high-frequency, high-current switching waveform - requires short, wide routing away from noise-sensitive nodes. |
| 2 PGND | Power Ground | Return path for high-current boost stage; must be separated from AGND and joined at single point near EP. |
| 3 IN | Input Supply | Accepts 2.5–5.5V input; requires ≥1 µF ceramic capacitor to AGND placed adjacent to pin for clean gate drive and control supply. |
| 4 AGND | Analog Ground | Reference for control loop and feedback; connects to EP and joins PGND at one point to minimize noise coupling. |
| 5 OUTS | Output Sense (Fixed) | Internally tied to OUT for regulation; not used in adjustable versions - confirms fixed 5.0V output configuration. |
| 6 EN | Enable Input | Active-high logic control; internal 2.5 MΩ pull-down ensures safe default-off state when floating. |
| 7 /PG | Open-Drain Power Good | Active-low flag indicating VOUT ≥ 0.9×VOUT; requires external 1 MΩ pull-up and sinks ~90Ω when asserted. |
| 8 OUT | Regulated Output | Delivers 5.0V to load; requires ≥22 µF low-ESR ceramic capacitor to PGND placed adjacent to pin for transient response. |
| EP | Exposed Thermal Pad | Primary thermal path; must be soldered to AGND plane with ≥6 thermal vias for reliable operation at full load. |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional true load disconnect | Prevents reverse current flow and input-to-output leakage during shutdown - critical for battery-backed systems where input may remain live while output is isolated. |
| Integrated anti-ringing switch | Clamps SW node to IN during DCM to suppress inductive ringing - reduces EMI without external snubbers or ferrite beads. |
| Automatic bypass mode | Enables direct IN-to-OUT conduction when VIN ≥ VOUT - eliminates switching losses and improves efficiency in high-input scenarios (e.g., USB-C PD input). |
| PFM at light loads | Enters pulse-skipping mode below ~100 mA to sustain >85% efficiency down to microamp loads - extends runtime in idle states. |
| Thermal shutdown with hysteresis | Shuts down at 155°C with 15°C hysteresis - prevents thermal runaway while allowing recovery without system reset. |
Applications
| USB OTG Power Delivery | Portable Power Reserve Supplies |
|---|---|
Use Scenario: Providing regulated 5V power from a single-cell lithium battery (3.0–4.2V) to enable USB On-The-Go functionality in smartphones or tablets.

IC Role / Device Role / Timing Role: Compact 2 MHz boost converter with soft-start and power-good signaling - ensures controlled rail ramp-up and system-level power sequencing. Use Value: 1.1 ms soft-start limits inrush current; /PG signal enables processor-based power management and fault detection. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous boost regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61236PDSGR | Fixed 5.0V output, 4.5A switch, 2.5 MHz, no bypass mode, no bi-directional disconnect | Lacks true load disconnect and automatic bypass - requires external load switch for isolation; higher quiescent current (2.5 µA) | Choose when higher switching frequency is prioritized over leakage control and bypass efficiency. |
| MAX17222ATA+T | Adjustable/fixed 5.0V option, 2.5A switch, 1.2 MHz, no bi-directional disconnect, no anti-ringing | Lower current capability and no integrated anti-ringing switch - needs external EMI mitigation; limited to ≤1.5A continuous output | Choose for cost-sensitive, lower-power applications where 2.5A peak suffices and EMI filtering can be added externally. |
Compared with TPS61236PDSGR and MAX17222ATA+T, the MIC2876-5.0YMT-T5 uniquely combines 4.8A current capability, bi-directional disconnect, automatic bypass, and integrated anti-ringing in a 2 mm × 2 mm UDFN - making it optimal for space-constrained, battery-critical portable designs demanding zero leakage and maximum efficiency across input voltage ranges.

FAQ
What is the output voltage tolerance of the MIC2876-5.0YMT-T5?
The MIC2876-5.0YMT-T5 has a fixed 5.0V output with ±1.5% accuracy over temperature and load conditions, as specified in the electrical characteristics table under "Voltage Accuracy" for the fixed-output version. This tolerance ensures compatibility with USB 2.0/3.0 VBUS requirements and downstream 5V logic interfaces without external trimming.
Does the MIC2876-5.0YMT-T5 support automatic bypass mode, and how does it work?
Yes, the MIC2876-5.0YMT-T5 automatically enters bypass mode when VIN ≥ VOUT (i.e., ≥5.0V), turning off the NMOS switch and fully enhancing the PMOS to create a low-impedance path from IN to OUT. This eliminates switching losses and improves efficiency - confirmed in the functional description and Figure 2-20/2-21 of the datasheet.
What is the maximum continuous output current achievable with the MIC2876-5.0YMT-T5?
The MIC2876-5.0YMT-T5 supports up to ~2.2A continuous output current at 5.0V under typical PCB thermal conditions (1-inch² copper, 2 oz, with EP connected), based on its 4.8A peak switch current limit, 90°C/W θJA, and thermal shutdown threshold of 155°C. Actual current depends on layout, ambient temperature, and input voltage - see Equation 7-2 in the datasheet for junction temperature calculation.
How does the bi-directional load disconnect function in the MIC2876-5.0YMT-T5 prevent leakage?
The MIC2876-5.0YMT-T5 uses an NMOS/PMOS power stage with a dedicated control circuit that turns off the PMOS back-gate diode during shutdown. An "always-on" maximum supply selector ensures the cathode of that diode is tied to whichever of IN or OUT is higher - blocking reverse current in both directions, even with as low as 0.3V on IN, as detailed in Section 5.2.
Is an external feedback resistor divider required for the MIC2876-5.0YMT-T5?
No - the MIC2876-5.0YMT-T5 is the fixed-output variant with internal feedback network tied to the OUTS pin, eliminating the need for external resistors. The adjustable version (e.g., MIC2876-ADJ) uses the FB pin and requires a resistor divider; this distinction is clearly shown in the pin function table and typical application schematics on pages 2 and 4 of the datasheet.
