What are the key features of MCP1252-33X50I/MS?
- 120mA regulated charge pump output at fixed 3.3V from 2.1V to 5.5V input using switched-capacitor architecture without inductors
- PWM control technique for stable regulation across the full 2.1V to 5.5V input range, compatible with 2xAA and Li-ion sources
- 8-pin MSOP package with optional 5V output variant enabling flexible voltage selection in a minimal PCB footprint
What is MCP1252-33X50I/MS used for?
The MCP1252-33X50I/MS is suited for battery-powered portable devices requiring a regulated 3.3V supply from 2xAA alkaline or single-cell Li-ion batteries where a small inductor-free charge pump is preferred over a boost converter. Its 2.1V minimum input voltage allows operation throughout the full discharge of alkaline cells, extending battery runtime in handheld instruments and wireless sensor nodes. The MSOP-8 package keeps PCB footprint minimal in wearable and compact embedded designs.

Frequently Asked Questions
What input voltage range does the MCP1252-33X50I/MS support and what is its maximum output current?
The MCP1252-33X50I/MS operates from an input voltage range of 2.1V to 5.5V and delivers up to 120mA output current at 3.3V. This input range covers 2xAA alkaline batteries from fresh (3V) down to near end-of-discharge at 2.1V, enabling extended battery life in portable applications.
How does the switched-capacitor topology of MCP1252-33X50I/MS compare to an inductor-based boost converter for noise-sensitive designs?
The MCP1252-33X50I/MS uses a switched-capacitor charge pump that requires only external capacitors, eliminating the magnetic components needed by boost converters. This reduces EMI compared to inductor switching and simplifies layout, although the charge pump is limited to 120mA output current versus higher-current boost converters.
Can the MCP1252-33X50I/MS be used with a single lithium coin cell as the input power source?
A single CR2032 lithium coin cell starts at 3V and discharges to approximately 2.2V, which falls within the 2.1V to 5.5V input range of MCP1252-33X50I/MS. The charge pump can therefore sustain 3.3V regulated output at up to 120mA throughout most of the coin cell's capacity, though coin cell internal resistance limits peak current to well below 120mA.
