SC4609: Low-Input, MHz Operation, High-Efficiency Synchronous Buck | Semtech

The SC4609 is a voltage mode step down (buck) regula- tor controller that provides accurate high efficiency power conversion from an input supply range of 2.7V 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 SC4609 is capable of producing an output voltage as low as 0.5V. The SC4609 drives external, N-Channel MOSFETs with a peak Gate current of 1A. A non-overlap protection is pro- vided for the Gate drive signals to prevent shoot through of the MOSFET pair. The SC4609 features lossless cur- rent sensing of the voltage drop across the drain to source resistance of the high side MOSFET during its conduction period. Its switching frequency CAN be pro- grammed up to 1MHz. By Semtech Corporation
