1 / 11 page  1.5MHz STEP-UP DC-DC CONVERTER AP3012 1 Oct. 2009 Rev. 1. 5 BCD Semiconductor Manufacturing Limited Data Sheet General Description 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-23-5 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 Small Inductor Applications · LCD/OLED Display Bias Supply · White LED Driver for LCD Display Backlights · Cellular Phones Figure 1.
