NCP3011: Synchronous PWM Controller

The NCP3011 is a Synchronous Buck Controller designed to operate from a wide input range and is capable of producing an output voltage as low as 0.8 V. The NCP3011 provides a 1.0 A gate driver and an internally set 400 kHz oscillator. The NCP3011 has an externally compensated transconductance error amplifier with an internally fixed soft-start. The NCP3011 incorporates output voltage monitoring with a PowerGood pin to indicate that the system is in regulation. The dual function SYNC pin synchronizes the device to a higher frequency (Slave Mode) or outputs a 180 out-of-phase clock signal to drive another NCP3011 (Master Mode). Protection features include lossless current limit and short circuit protection, output overvoltage and undervoltage protection, and input undervoltage lockout. The NCP3011 is available in a 14-pin TSSOP package.
