STR-X6759N

AC DC Converters, Offline Switchers Overview

The STR-X6759N is a switching power supply thick film circuit manufactured by Sanken Electric. It integrates an oscillator, error amplifier, voltage regulation control circuit, drive circuit, and a high-power MOSFET switch tube into a single unit. The component utilizes a 7-pin vertical package design. In practical applications, such as the main switching power supply circuit for Changhong GP02 LCD TV power boards, it operates by receiving a startup voltage at pin 4. When this voltage reaches 18.2V, the internal oscillation circuit activates to generate switching pulses, enabling the main power supply to enter normal operation.
