Philips NE/SE5561 Switched-Mode Power Supply Control Circuit Datasheet
The NE/SE5561 is a control circuit designed for low‑cost switched‑mode power supply applications. It integrates a temperature‑compensated reference, PWM, sawtooth oscillator, over‑current sense latch and output stage. The device is offered in several 8‑pin packages (DIP, CERDIP, SO) and supports both voltage‑forced and current‑fed operation.
Key specifications include a +18 V forced‑mode supply voltage, 40 mA maximum output current, 1.4 V output voltage, 98 % duty‑cycle capability and a 0.75 W power‑dissipation limit. The SE5561 version operates from –55 °C to +125 °C, while the NE5561 version covers 0 °C to +70 °C. Typical performance curves and start‑up guidelines are provided for designing reliable power converters.
