1 / 16 page ![]() 150kHz 3A BUCK DC-DC CONVERTER AP3003 Data Sheet 1 Feb. 2007 Rev. 1. 1 BCD Semiconductor Manufacturing Limited General Description 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 regula- tion. These regulators include internal frequency com- pensation and a fixed frequency oscillator so that they are easy to use. A system adopting AP3003 requires a minimum number of external components to work. A standard series of inductors, optimized for use with the AP3003 series, are available from several manu- facturers. This feature greatly simplifies the design of switch-mode power supplies. These ICs are available in TO-220-5 and TO-263-5 packages. Features · 3.3V, 5V, 12V Fixed ( ±4% Tolerance) and Adjust- able ( ±3% Tolerance) Output Versions · Guaranteed 3A Output Load Current · 150kHz Fixed Frequency Internal Oscillator · Input Voltage Range up to 32V · Requires only 4 external components · 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 Figure 1.
