BCT1202S -2A Step Down DC/DC Converter

GENERAL DESCRIPTION
The BCT1202S is a step down monolithic regulator with a built-in internal power MOSFET, capable of driving up to 2A continuous output current with excellent line and load regulation. The output voltage can be set from 0.8V to 16V.

Requiring a minimum number of external components, it offers simple to use, but high efficiency and advanced protection features including pulse-by-pulse current limiting and thermal shutdown. Adjustable soft-start reduces the stress on the input source at turn-on and the regulator draws only 20uA in shutdown mode.

BCT1202S is available in a Pb-Free SOIC8 package.
