1 / 14 page  Data Sheet Boost Controller for WLED Driver in Medium-sized LCD Panel AP3041 Oct. 2012 Rev. 1. 2 BCD Semiconductor Manufacturing Limited 1 General Description The AP3041 is a current mode high voltage low-side channel MOSFET controller, which is ideal for boost regulators. It contains all the features needed to implement single-ended primary topology DC/DC converters. The input voltage of AP3041 ranges from 5V to 27V. Its operation frequency is adjustable from 100kHz to 1MHz. The AP3041 has UVLO (Under Voltage Lock Out) circuit. It uses two external resistors to set the UVLO voltage. The AP3041 also has an over output voltage protection to limit the output voltage. The OVP voltage can be set through external resistors. If the output voltage is higher than the OVP high threshold point, it will disable the driver and the system is latched up. The output short circuit protection as well as LED low side short to ground detection function can be applied in system. The AP3041 has other protection functions, such as LED short protection, LED high side short to ground protection, diode short protection, over current protection, over temperature protection and so on. The AP3041 is available in SOIC-16 package. Features • Input Voltage Range: 5V to 27V • 1A Peak and 10V MOSFET Gate Driver • 20ns Quick MOSFET Gate Driver • Duty Cycle Limit of 90% • Programmable UVLO • PWM Dimming Control • Programmable Over Voltage Protection • LED Open Protection • LED Short Circuit Protection • Diode Short Circuit Protection • Output Short Circuit Protection • LED Low-side Short to Ground Detection • OV Pin Under Voltage Protection • Over Current Protection • Programmable Slope Compensation • Adjustable Soft-start • Adjustable Protection Delay • Fault Status Indication • Adjustable Operation Frequency from 100kHz to 1MHz • Over Temperature Protection Applications • LED Lighting • LED TV • LCD Display Modules Figure 1.
