1. Introduction
- Typical model usage (e.g., BN44-00264A, LAD711P Rev 1.0/1.1/1.4)
- Input: 100–240V AC → Output: 5VSB, 5V, 12V, 24V, (sometimes 13V for audio)
- Primary-side vs. secondary-side regulation
Overview — LAD711P Rev 10 Schematic (Top)
LAD711P Rev 10 appears to be a revision of a circuit board whose top-side schematic shows component placement, signal routing, and key interfaces. Below is a concise, structured guide to reading and understanding the top-side schematic for this revision.
Zone E: Feedback & Protection Logic (Top Right)
The LAD711P Rev 10 includes a supervisor IC (LM393 dual comparator or TL431). The top schematic shows:
- Voltage Divider: Resistors R31, R32 tap the +5V rail.
- TL431: Drives the PC817 optocoupler. The cathode connects to the opto's LED.
- Over-Voltage Protection (OVP): A crowbar circuit using an SCR (BT151) across the +24V output. If voltage exceeds 28V, the SCR shorts and blows the primary fuse.
- Power Good (PG) Signal: An open-collector output used by the host system.
