SC16C650AIA44D - Brand New IC Chips
-
Description
The SC16C650AIA44D is a high-performance inverting DC-DC converter designed for generating programmable negative voltages. It is particularly suitable for LCD bias contrast applications and can achieve a maximum efficiency of 90% with low-cost PNP bipolar transistor drivers. The input operation range is 4V to 24V, allowing it to be directly powered by the battery pack in most battery-operated applications for 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.
