The AP8269SEC-R1 with Switching Controllers SOP-8_150mil RoHS manufactured by Chipown is a low-voltage, low-cost single-channel, bidirectional, synchronous step-down switching controller with a wide 4.5V to 24V input voltage range. It is designed to provide a simple, low-cost solution for powering widely used devices such as TVs, STBs, point-of-sale systems, routers, and VoIP phones. It provides accurate output voltage regulation and protection features such as over-voltage, under-voltage, and thermal shutdown. The AP8269SEC-R1 has a programmable output voltage range from 0.765V to 20.5V and a duty cycle (DMAX,DINF) from 0.1% to 99.9%. It also has built-in overtemperature protection. The device is compliant to RoHS and available in an 8-pin surface-mount SOP-8 (150-mil) package.
