SC4605: Low-Input, High-Efficiency Synchronous Step-Down Controller | SemtechThe SC4605 is a voltage mode step down (buck) regula-
tor controller that provides accurate high efficiency power
conversion from a input supply range of 2.8V 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 SC4605 drives external N-Channel MOSFETs with 1A
peak current. A non-overlap protection is provided for
the Gate drive signals to prevent shoot through of the
MOSFET pair. The voltage drop across the high side
MOSFET during its conduction is sensed for lossless short
circuit current limiting. By Semtech Corporation
