Features
*
BICMOS Voltage mode PWM controller 2.75V to 5.5V Input voltage range Output voltages as low as 0.8V +/-1% Reference accuracy Sleep Mode (Icc = 10µA typ) Lossless short circuit current limiting Combination pulse by pulse & hiccup mode current limit High efficiency synchronous sw
Applications
* where cost, size and efficiency are critical. The SC4602A/B 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 MOSFET eliminates the need for an external charge pump and simplifies the high side ga
