The AP3012 is a high power, constant frequency, cur-
rent mode PWM, inductor based, step-up (boost) con-
verter. 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 goes into shutdown mode when the
output voltage exceeds the OVP threshold of 29V.
The AP3012 is available in standard SOT-23-5L pack-
age.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 Dur-
ing Start-up
· On-chip Overvoltage Protection
· Uses Low ESR Ceramic Output Capacitor
· Uses Smll Inductor
Applications
· LCD/OLED Display Bias Supply
· White LED Driver for LCD Display Backlights
· Cellular Phones
