Product Summary

The A6151 is a PRC topology (fixed off-time) regulator specifically designed to satisfy the requirements for increased integration and reliability in flyback converters. It incorporates a primary control and drive circuit with avalanche-rated power MOSFETs. The A6151 features higher switching current and avalanche-energy ratings and lower on-resistance.

Parametrics

A6151 absolute maximum ratings: (1)Control Supply Voltage, VCC: 35 V; (2)Drain-Source Voltage, VDSS: 650 V; (3)Drain Switching Current, ID: 2.5 A; (4)Peak Drain Switching Current, IDM: 2.5 A; (5)Single-Pulse Avalanche Energy, EAS: 72 mJ; (6)Start-Up-Pin Voltage Range, Vstartup: -0.3 V to +600 V; (7)OCP Voltage Range, VOCP: -0.5 V to +6 V; (8)FB/OLP Voltage Range, VFB/OLP: -0.5 V to +10 V; (9)MOSFET Channel Temp., TJ: +150℃; (10)Internal Frame Temp., TF: +125℃; (11)Storage Temperature Range, TS: -40℃ to +125℃.

Features

A6151 features: (1)Rugged 650 V Avalanche-Rated MOSFET Simplified Surge Absorption No VDSS Derating Required; (2)Choice of rDS(on) (3.95 Ω or 6 Ω maximum); (3)Two Operational Modes by Automatic Switching: PRC Mode for Normal Operation; Burst Mode for Stand-By Operation or Light Loads; (4)Built-In Leading Edge Blanking; (5)Low Start-Up Current Start-Up Circuit Disabled in Operation; (6)Low Operating Current (1.5 mA typ); (7)Automatic Burst Stand-By(intermittent operation)Input Power <0.1 W at No Load.
