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