4. Circuit Description (VE510s-4/VE510b-4) A. AC-DC CONVERTER The power supply with a high-integrated green-mode PWM controller provides several features to enhance the performance of power flyback converters. I801 is a PWM controller and provides many protection functions. I802 is a photo couple to transfer the feedback signal from the second side which I803 detected both of the output DC voltage on 3.3V and 12V.

■ PWM Interface: (PWM1, PWM2 can be selected from 1 of 3 possible pins.
C. MTV312M64 The MTV312M micro-controller is an 8051 CPU core embedded device especially tailored for CRT/LCD Monitor applications. It includes an 8051 CPU core, 1024-byte SRAM, 14 built-in PWM DACs, VESA DDC interface, 4-channel A/D converter, and a 64K-byte internal program Flash-ROM. A “CMOS output pin” means it can sink and drive at least 4mA current. It is not recommended to use such pin as input function. A “open drain pin” means it can sink at least 4mA current but only drive 10~20uA to VDD.
5. Adjusting Procedure (VE510s-4/VE510b-4) 5.1. ADJUSTMENT CONDITIONS AND PRECAUTIONS 1. Approximately 30 minutes should be allowed for warm up before proceeding. 2.
