The AP3003S-3.3TRE1 from Diodes Incorporated is a fixed-frequency PWM buck (step-down) DC/DC converter. It is designed to drive a 3A load with excellent line and load regulation. This device features internal frequency compensation and a fixed frequency oscillator, simplifying design by requiring a minimum number of external components.
Key electrical specifications include a fixed 3.3V output voltage, a guaranteed 3A output load current, and a 150kHz internal oscillator. The input voltage range extends up to 32V, and it offers high efficiency up to 90%. It also includes a low power standby mode with a typical quiescent current of 80µA, built-in current limit protection, and thermal shutdown circuitry.
This converter is suitable for applications such as LCD monitors, LCD TVs, on-card DC-DC converters, DVD recorders, and PDPs. It is available in a TO-263-5 surface mount package, designed for ease of integration into power supply designs.
