The SC1652 is a high performance inverting DC-DC converter, designed to drive an external power switch to generate programmable negative voltages.

In the particularly suitable LCD bias contrast application, efficiency of 87% can be achieved with low cost PNP bipolar transistor drivers.

The output voltage can be scaled to -40V by two external resistors.

2.4V to 7V input voltage operation.
Adjustable output voltage up to -40V.
Low quiescent current at 80µA.
Pulse frequency modulation maintains high.
efficiency (max 87%) 70kHz to 160kHz switching frequency Power-saving shutdown mode (0.7µA typical) High efficiency with low cost external PNP bipolar transistor.
