Description: High Efficiency Synchronous Buck

Features

* BICMOS voltage mode PWM controller 2.25V to 5.5V Input voltage range Output voltages as low as 0.5V Sleep mode (Icc = 10µA typ) Lossless adjustable overcurrent protection Combination pulse by pulse & hiccup mode current limit High efficiency synchronous switchin

Applications

* where cost, size and efficiency are critical. The SC4603 drives external complementary power MOSFETs; P-channel on the high side and N-channel on www. DataSheet4U. com the low side. The use of high side P-channel MOSFETs eliminates the need for an external charge pump and simplifies the high side gate
