NCP3237MNTXG

The NCP3237 is a single−phase synchronous buck converter that integrates power MOSFETs to provide a high−efficiency and compact−footprint power management solution. This device is able to deliver up to 8 A output current over a wide output voltage range from 0.6 V to 12 V (up to 80% of VIN). The NCP3237 offers a fixed frequency regulator ideally suited for noise sensitive systems. NCP3237 is a single−phase synchronous buck converter with two integrated N−type power MOSFETs to provide a high−efficiency and compact−footprint power management solution. The device is able to deliver up to 8A output current over a wide output voltage range from 0.6 V to 0.8×VIN and no higher than 12 V. It has a wide input voltage range from 4.5 V to 16 V. The NCP3237 features include resistor adjustable frequency input to optimize the output filter size, an enable and power good indicator for sequencing and an internal soft−start function during the initial power up. These devices offer safe start up into a pre−biased output condition and offer multiple protection features including cycle−by−cycle high side and low side over−current limiting.
