Philips Semiconductors Product specification NE/SE5560Switched-mode power supply control circuit 11994 Aug 31 853-0125 13721 DESCRIPTION The NE/SE5560 is a control circuit for use in switched-mode power supplies. This single monolithic chip incorporates all the control and housekeeping (protection) functions required in switched-mode power supplies, including an internal temperature-compensated reference source, internal Zener references, sawtooth generator, pulse-width modulator, output stage and various protection circuits. FEATURES • Stabilized power supply • Temperature-compensated reference source • Sawtooth generator • Pulse-width modulator • Remote on/off switching • Current limiting • Low supply voltage protection • Loop fault protection • Demagnetization/overvoltage protection • Maximum duty cycle clamp • Feed-forward control • External synchronization PIN CONFIGURATION D, F, N Packages 1 2 3 4 5 6 7 8 9 10 11 12 13 14 16 15 VCC VZ FEEDBACK GAIN MODULATOR DUTY CYCLE CONTROL RT CT FEEDFORWARD OUTPUT (COLL) OUTPUT (EMIT) DEMAG: OVERVOLTAGE GND CURRENT LIMITING REMOTE ON/OFF EXTERNAL SYNC SL00360 Figure 1.
