General Description
The AP1522 is a step-up DC/DC converter in a
5-Lead low profile SOT23-5 package. The AP1522
switches at 1MHz that allows the use of tiny
external components. A low 1.25V feedback voltage
minimizes power loss in the current setting resistor
for better efficiency.
Applications
- Cellular Phones
- PDAs, Handhelp Computers
- Digital Cameras
- LCD Bias Voltage, Battery Backup
