AP3003 Datasheet | BCD Semiconductor

Data Sheet 150k Hz 3A BUCK DC-DC CONVERTER General Description Features The AP3003 series of regulators are fixed frequency PWM buck (step-down) DC/DC converter, capable of driving a 3A load with excellent line and load regulation. These regulators include internal frequency pensation and a fixed frequency oscillator so that they are easy to use. A system adopting AP3003 requires a minimum number of external ponents to work. A standard series of inductors, optimized for use with the AP3003 series, are available from several manufacturers. This feature greatly simplifies the design of switch-mode power supplies. These ICs are available in TO-220-5 and TO-263-5 packages. - 3.3V, 5V, 12V Fixed (±4% Tolerance) and Adjustable (±3% Tolerance) Output Versions - Guaranteed 3A Output Load Current - 150k Hz Fixed Frequency Internal Oscillator - Input Voltage Range up to 32V - Requires only 4 external ponents - High Efficiency up to 90% - Excellent Line and Load Regulation - TTL Shutdown Capability - Low Power Standby Mode, IQ Typically 80µA - Built-in Current Limit Protection and Thermal Shutdown Circuit Applications - LCD Monitor and LCD TV - On-Card DC-DC Converter - DVD Recorder - PDP TO-220-5 TO-263-5 Aug. 2008 Rev. 1. 2 Figure 1.
