High Efficiency Synchronous, Step Down Controller POWER MANAGEMENT Description The SC4602A/B is a voltage mode step down (buck) regulator controller that provides accurate high efficiency power conversion from an input supply range of 2.75V to 5.5V. A high level of integration reduces external component count and makes it suitable for low voltage 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 gate driver. Non-overlap protection is provided for the gate drive signals to prevent shoot through of the MOSFET pair.
