The magic of a regulated power supply lies in the feedback loop. On the , trace the output voltage (20V) through a voltage divider (resistors) into a TL431 programmable shunt regulator.
IC to generate the low-power standby rail independently of the main 12V supply. Main Switching Stage (+12V): Employs high-power Mosfets (like the STB33N65M2 PWM controller to drive the main transformer. Common Failures & Repair Tips ADP-160ER PS4 Power Supply Repair 07-Aug-2018 — Adp-160er Schematic
On the primary side, the optocoupler’s phototransistor conducts more current, pulling the FB pin of the PWM controller low. The PWM responds by reducing the duty cycle (shortening the on-time of the MOSFET), which lowers the output voltage back to 20V. The magic of a regulated power supply lies
The ADP-160ER schematic is a vital resource for anyone working with this IC. By studying the schematic, engineers and designers can: The ADP-160ER schematic is a vital resource for
Rated at approximately 13A . This powers the APU (CPU/GPU), Blu-ray drive, and fan.
Tracing the schematic reveals several safety sub-circuits:
: It provides vital identification for standard failure points like primary MOSFETs, standby voltage regulators, and filter capacitors. 👍 The Good
