AP1522
Features
- High Efficiency: 84% Typical
- 36V High Output Voltage
- Fast 1MHz Switching Frequency
- Low Profile SOT23-5 Pb-Free Packaging
- 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 ponents. A low 1.25V feedback voltage minimizes power loss in the current setting resistor for better efficiency.
- Applications
- Cellular Phones
- PDAs, Handhelp puters
- Digital Cameras
- LCD Bias Voltage, Battery Backup
- - Pin Assignments
