150KHz, 3A PWM BUCK DC/DC CONVERTER

APEC - Buck DC/DC Converter APE1702 The APE1702 series are monolithic IC designed for a Step-down DC/DC converter, and own the ability of driving a 3A load without additional Transistor It saves board space. The external shutdown function CAN be controlled by Logic level and then come into standby mode. The internal compen- sation makes feedback control having good line and load regulation without external design. Regarding protected function, thermal shutdown is to prevent over temperature operating from damage, and current limit is against over current operating of the output Switch if current limit function occurs and VFB is down below 0.5V the switching frequency will be reduced. The APE1702 series operates at a switching frequency of 150KHz thus allow smaller sized Filter components than what would be needed with lower frequency Switching Regulators Other features include a guaranteed +4% tolerance on output voltage under specified input voltage and output load con- ditions, and +15% on the Oscillator frequency. The output version included fixed 3.3V, 5V, 12V and an adjustable type. The chips are available in a 5-Lead TO-263 and 5-Lead TO-220 package. By APEC
