1 / 19 page  BOOST CONTROLLER AP3039 Data Sheet 1 BCD Semiconductor Manufacturing Limited Dec. 2009 Rev. 1. 4 General Description AP3039 is a current mode high voltage low-side N- channel MOSFET controller which is ideal for boost regulators. It contains all the features needed to imple- ment single ended primary topology DC/DC converters. The input voltage range of AP3039 is from 5V to 27V. Its operation frequency is adjustable from 200kHz to 1MHz. The AP3039 has UVLO (Under Voltage Lock Out) circuit. It uses two external resistors to set the UVLO voltage. The AP3039 also has an over output voltage protection to limit the output voltage. The OVP volt- age can be set through external resistors. If the output voltage is higher than the OVP high threshold point, it will disable the driver, when the output voltage drops to the OVP low threshold point, it will enable the driver. It also features a soft start to reduce the inrush current when power on, the soft start time can be set through an external capacitor. The AP3039 is available in QFN-3x3-16 and SOIC-14 packages.
