- Wide input voltage range of 2.1 V to 5.5 V enabling operation from single-cell Li-Ion or two-cell alkaline batteries
- Compact MSOP-8 package with only 2 external capacitors required, minimizing BOM and board space
Applications
The MCP1253-33X50I/MS is ideal for portable consumer electronics and handheld instruments that require a stable 3.3 V rail from a Li-Ion or alkaline battery operating down to 2.1 V. Its PWM charge-pump topology produces low switching noise, making it suitable for powering ADCs, RF front-ends, and other noise-sensitive analog loads up to 120 mA. The MSOP-8 form factor also fits space-constrained wearable and IoT sensor designs needing efficient regulated voltage conversion.

Frequently Asked Questions
What output current can the MCP1253-33X50I/MS supply, and at what output voltage?
The MCP1253-33X50I/MS provides a regulated 3.3 V output with a maximum output current of 120 mA, making it suitable for powering microcontrollers, sensors, and low-power RF modules from battery-based systems.
Which battery chemistries are compatible with the MCP1253-33X50I/MS input voltage range?
With an input voltage range of 2.1 V to 5.5 V, the device works with single-cell Li-Ion batteries (discharged to 2.5 V), two-cell alkaline packs, and USB 5 V rails, covering the most common portable power sources without additional regulation.
How does the PWM control technique of the MCP1253-33X50I/MS benefit noise-sensitive analog designs?
PWM control operates at a fixed switching frequency, generating predictable spectral noise that designers can filter with small capacitors. This allows MCP1253-33X50I/MS to power 12-bit or 16-bit ADCs and precision op-amps with minimal interference compared to PFM-only converters that have variable noise spectra.
How many external components does the MCP1253-33X50I/MS require, and what package is used?
The MCP1253-33X50I/MS comes in an MSOP-8 package and requires only 2 external flying capacitors and 1 output capacitor, keeping the total solution footprint under 20 mm² for compact portable device designs.
