Overview
| Topology | Boost Converter |
| Input voltage | 2.6-16 V |
| Output 1 | 24 V / 0.03 A |
| IC revision | 1.1 |
Description
The AP3012 is a high power, constant frequency, current mode PWM, inductor based, step-up (boost) converter. The converter operates at high frequency (1.5MHz) so that a small, low profile inductor can be used. The AP3012 has built-in overvoltage protection (OVP) to allow the device to go into shutdown mode when the output voltage exceeds the OVP threshold of 29V. The AP3012 is available in standard SOT25 package.
Features
- High Efficiency up to 81%
- Adjustable Output Voltage up to 29V
- Shutdown Current 1μA Typical
- 1.5MHz Switching Frequency
- 36V 500mA Rugged Integrated Bipolar Switch
- Built-in Soft-start to Reduce Inrush Current During Start-up
- On-chip Overvoltage Protection
Typical applications
- LCD/OLED Display Bias Supply
- White LED Driver for LCD Display Backlights
- Cellular Phones
