SC4601: Low-Input, High-Efficiency Synchronous Step-Down Controller | Semtech

The SC4601 is a voltage mode step down (buck) regula- tor controller that provides accurate high efficiency power conversion from input supply range 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 SC4601 drives external complementary power MOSFETs; P-channel on the high side and N-channel on 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 driver. Non-overlap protec- tion is provided for the Gate drive signals to prevent shoot through of the MOSFET pair. The voltage drop across the P-Channel MOSFET during its conduction is sensed for lossless short circuit current limiting. By Semtech Corporation
