What are the key features of MCP16252T-I/CH?
- Ultra-low startup voltage of 0.82 V enables operation from a single alkaline or NiMH cell
- Synchronous rectification improves efficiency, reducing power loss versus diode-based boost converters
- Fixed PWM switching frequency of 2 MHz minimizes external inductor and capacitor size
- Adjustable output voltage with external resistor divider from 1.8 V to 5.5 V covers common logic supply rails
- 6-pin SOT-23 package in a compact footprint for wearable and coin-cell powered applications
What is MCP16252T-I/CH used for?
The MCP16252T is designed for single-cell battery-powered applications such as wireless sensor nodes, fitness trackers, and BLE beacons that start and operate from a single alkaline or NiMH cell delivering as little as 0.82 V. Its 2 MHz switching frequency allows the use of small inductors in the 4.7 µH to 10 µH range, keeping the overall power module compact. Energy harvesting platforms collecting energy from thermoelectric generators or solar micro-cells also use this converter to step up low input voltages to 3.3 V or 5 V rails.

Frequently Asked Questions
What is the minimum startup voltage of MCP16252T and how does it support single-cell battery designs?
MCP16252T starts up from an input as low as 0.82 V, enabling operation from a single alkaline or NiMH cell even as the battery discharges below 1 V. This allows IoT sensor nodes and BLE devices to extend usable battery life far beyond the typical 1.0 V cutoff of non-boost regulators.
What switching frequency does MCP16252T use and how does it affect inductor selection?
The MCP16252T operates at a fixed 2 MHz PWM switching frequency, which allows the use of compact inductors in the 4.7 µH to 10 µH range and small ceramic output capacitors below 10 µF. This reduces total solution size significantly compared to lower-frequency converters requiring larger magnetics in a 6-pin SOT-23 power module.
Which energy harvesting circuits can use MCP16252T to generate a 3.3 V rail from low-voltage sources?
Thermoelectric generators, small solar cells, and RF energy harvesting circuits producing 0.82 V to 2 V output are compatible with MCP16252T as the boost stage to a 3.3 V regulated supply. The device's synchronous rectification improves conversion efficiency above 85%, maximizing the usable energy extracted from low-power harvesting sources.
How should the output voltage of MCP16252T be set for a 5 V USB-compatible output?
Output voltage is set by an external resistor divider connected to the feedback pin, with a reference voltage of approximately 0.41 V. For a 5 V output from a 1.5 V input alkaline cell, a resistor ratio of roughly 11:1 on the divider programs the MCP16252T to regulate at 5 V, within its 5.5 V maximum output rating.
