MCP1252/3

Low Noise, Positive-Regulated Charge Pump

Features

Description

• Inductorless, Buck/Boost, DC/DC Converter

• Low Power: 80 µA (Typical)

• High Output Voltage Accuracy:

The MCP1252/3 are inductorless, positive-regulated

charge pump DC/DC converters. The devices generate

a regulated fixed (3.3V or 5.0V) or adjustable output

voltage. They are specifically designed for applications

requiring low noise and high efficiency and are able to

deliver up to 120 mA output current. The devices allow

the input voltage to be lower or higher than the output

voltage, by automatically switching between buck/

boost operation.

The MCP1252 has a switching frequency of 650 kHz,

avoiding interference with sensitive IF bands. The

MCP1253 has a switching frequency of 1 MHz and

allows the use of smaller capacitors than the

MCP1252, thus saving board space and cost.

Both devices feature a power-good output that can be

used to detect out-of-regulation conditions. Extremely

low supply current and low external parts count (three

capacitors) make these devices ideal for small, battery-

powered applications. A shutdown mode is also pro-

vided for further power reduction. The MCP1252 and

MCP1253 feature thermal and short-circuit protection

and are offered in space-saving, 8-lead, MSOP

packages.
