NCP81045

NCP81045 Product Preview Single Synchronous Step-Down Controller The NCP81045 is a synchronous stepdown controller for high performance systems battery−power systems. The NCP81045 includes a high efficiency PWM controller. A pin is provided to allow two devices in interleaved operation. An internal power good voltage monitor tracks the SMPS output. NCP81045 also features soft−start sequence, UVLO for VCC and switcher, overvoltage protection, overcurrent protection, undervoltage protection and thermal shutdown. The IC is packaged in QFN16.
