MCP1252/3  
M
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.
