The SC1186 switching section features an integrated 5 bit D/A converter, latched drive output for enhanced noise immunity, pulse by pulse current limiting and logic compatible shutdown. The SC1186 switching section operates at a fixed frequency of 140kHz, providing an optimum compromise between size, efficiency and cost in the intended application areas. The integrated D/A converter provides programmability of output voltage from 2.0V to 3.5V in 100mV increments and 1.30V to 2.05V in 50mV increments with no external components.
