SC16C2550IB48 - Brand New PHILIPS UARTs (Universal Asynchronous Receiver Transmitter)
-
Description
The SC16C2550IB48 is a high performance inverting DC-DC converter designed for driving an external power switch to generate programmable negative voltages. It is particularly suitable for LCD bias contrast applications, with a maximum efficiency of 90% achieved using low-cost PNP bipolar transistor drivers. With an input operation range of 4V to 24V, it can be directly powered by the battery pack in most battery-operated applications for greater efficiency. The output voltage can be scaled to -40V by using two external resistors. The SC16C2550IB48 utilizes a pulse frequency modulation scheme to maintain high efficiency conversion under wide input voltage ranges. It has a quiescent current of about 100µA, which can be reduced to 8µA in shutdown mode. Its switching frequency range is from 100kHz to 320kHz, making it ideal for battery-powered portable equipment such as notebook and palmtop computers.
