The NCP3020A, NCP3020B, and NCP3011 synchronous PWM controllers offer a 4.7 to 28-V input voltage range and suit set-top-boxes and LCD televisions, as well as industrial and computing applications.
The PWM controllers provide a 1-A integrated gate drive and can produce output voltages as low as 0.6 V (NCP3020A and NCP3020B) and 0.8 V (NCP3011). The NCP3011 also provides a buffered +1.25-V reference voltage. An internal oscillator sets the operating frequencies of 300 kHz (NCP3020A), 600 kHz (NCP3020B), and 400 kHz (NCP3011). The controllers have an integrated boost drive clamp to regulate the driver supply voltage to 7.6 V. The NCP3011 includes dual-level power-good, an enable/disable pin, and external synchronization. (Ea/10,000: NCP3020A and NCP3020B, $0.30; NCP3011, $0.53 available now.)
