IL44608N

TECHNICAL DATA External Components Reliable and Flexible SMPS Controller DESCRIPTION The IL44608N is a high performance voltage mode controller designed for off–line converters. This high voltage circuit that integrates the start–up current source and the oscillator capacitor, requires few external components while offering a high flexibility and reliability. The device also features a very high efficiency stand–by management consisting of an effective Pulsed Mode operation. This technique enables the reduction of the stand–by power consumption to approximately 1.0 W while delivering 300 mW in a 150 W SMPS. ● Integrated Start–Up Current Source ● Lossless Off–Line Start–Up ● Direct Off–Line Operation ● Fast Start–Up General Features ● Flexibility ● Duty Cycle Control ● Under-voltage Lockout with Hysteresis ● On Chip Oscillator Switching Frequency 40, 75, or 100 kHz ● Secondary Control with Few External Components Protections ● Maximum Duty Cycle Limitation ● Cycle by Cycle Current Limitation ● Demagnetization (Zero Current Detection) Protection ● “Over VCC Protection” Against Open Loop ● Programmable Low Inertia Over Voltage Protection against Open Loop ● Internal Thermal Protection SMPS Controller ● Pulsed Mode Techniques for a Very High Efficiency Low Power Mode ● Lossless Startup ● Low dV/dT for Low EMI Radiations www.DataSheet4U.com IL44608N PACKAGE PDIP-8 Pin Connection Ordering Information Device IL44608N40 IL44608N75 IL44608N100 Switching Frequenc...
