Key Features
- Adjustable output voltage via external resistor divider, enabling flexible regulation from a single charge-pump topology
- 120 mA continuous output current capacity with 2 V to 5.5 V input range, supporting 3.3 V and 5 V rail applications
- PWM control in compact 8-pin MSOP package, minimizing solution footprint in space-constrained designs
Applications
The MCP1252-ADJI/MS is suited for battery-powered portable devices that need a regulated boosted rail, such as LCD bias supplies, white-LED drivers, and SRAM backup circuits. Its adjustable output and wide 2 V to 5.5 V input range make it practical for single-cell Li-ion or AA-cell applications where supply voltage varies over the discharge cycle. The small 8-pin MSOP footprint also makes it a good fit for wearables and IoT sensor nodes where board area is tightly constrained.

Frequently Asked Questions
What input voltage range does the MCP1252-ADJI/MS support, and how does that affect battery selection?
The MCP1252-ADJI/MS accepts inputs from 2 V to 5.5 V, making it compatible with single-cell Li-ion batteries (2.7 V to 4.2 V) and two-cell AA alkaline packs (2 V to 3.2 V). This 2 V minimum threshold allows the converter to keep operating well into battery discharge, extending usable runtime in portable equipment.
How much output current can the MCP1252-ADJI/MS deliver, and what loads is that sufficient for?
The device delivers up to 120 mA continuous output current, which is adequate for driving a small LCD module (typically 20 mA to 80 mA), several white LEDs in parallel, or powering low-power microcontrollers and sensors on a boosted rail. Loads requiring more than 120 mA will need a higher-current charge pump or a switching regulator instead.
Why choose an MSOP-8 charge pump over a larger SOT-23 or DIP alternative for a compact PCB?
The 8-pin MSOP package measures approximately 3 mm x 3 mm, significantly smaller than an 8-pin DIP (about 10 mm x 7 mm), and comparable in area to SOT-23 multi-chip solutions. Fewer external components are needed compared to an inductor-based converter, and the MSOP-8 footprint allows single-layer PCB routing in designs with as little as 10 mm² allocated to the power supply section.
How is the output voltage set on the MCP1252-ADJI/MS, and what resistor values are typically used?
Output voltage is set with an external resistor divider connected to the feedback pin. Using standard 1% resistors, a top resistor of 100 kΩ and a bottom resistor calculated from the formula VOUT = VREF × (1 + R1/R2) allow outputs between the internal reference voltage and approximately 2× the input voltage, covering common target rails of 3.3 V and 5 V within the 2 V to 5.5 V input window.
