Description
The SC1159 is a synchronous-buck switch-mode controller designed for use in single ended power supply applications where efficiency is the primary concern.
The controller is a hysteretic type, with a user selectable hysteresis.
Features
- include an integrated 5 bit D/A converter, temperature compensated voltage reference, current limit comparator, over-current protection, and an adaptive deadtime circuit to prevent shoot-through of the power MOSFET during switching transitions. Power good signaling, logic compatible shutdown, and over-voltage protection are also provided. The integrated D/A converter provides programmability of output voltage from 1.050V to 1.825V in 25mV increments. The SC1159 high side driver can be configured.
