Description
The SC16C1654BIB64+151 is a high performance inverting DC-DC converter. It is designed to drive an external power switch to generate programmable negative voltages. The converter is particularly suitable for LCD bias contrast applications, where it can achieve maximum efficiency of 90% with low cost PNP bipolar transistor drivers. With an input operation range of 4V to 24V, the SC16C1654BIB64+151 can be directly powered by the battery pack in most battery-operated applications, resulting in greater efficiency. The output voltage can be scaled to -40V using two external resistors. It employs a pulse frequency modulation scheme to maintain high efficiency conversion under wide input voltage ranges. The quiescent current is about 100µA and can be reduced to 8µA in shutdown mode. With a switching frequency range of 100kHz to 320kHz, it is ideal for battery-powered portable equipment such as notebook and palmtop computers.
