SC4603 buck equivalent, high efficiency synchronous buck.
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) Loss.
where cost, size and efficiency are critical. The SC4603 drives external complementary power MOSFETs; P-channel on the h.
The SC4603 is a voltage mode step down (buck) regulator controller that provides accurate high efficiency power conversion from input supply range 2.25V to 5.5V. A high level of integration reduces external component count and makes it suitable for l.
