The NCP3011 is a synchronous buck controller suitable for operation over a wide input range and capable of generating output voltages 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 internal fixed soft-start. The NCP3011 combines 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 uses a 14-pin TSSOP encapsulation.
