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 beused.The AP3012 has built-in overvoltage protection (OVP)to allow the device goes into shutdown mode when theoutput 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 InductorApplications· LCD/OLED Display Bias Supply· White LED Driver for LCD Display Backlights· Cellular Phones
