SC16C654BIEC - Brand New PHILIPS UARTs (Universal Asynchronous Receiver Transmitter)
-
Description
The SC16C654BIEC is a high-performance UART (Universal Asynchronous Receiver Transmitter) electronic component. It is designed to drive an external power switch to generate programmable negative voltages, making it particularly suitable for LCD bias contrast applications. With a maximum efficiency of 90%, this model can achieve high performance with low-cost PNP bipolar transistor drivers. It has an input operation range from 4V to 24V, allowing it to be powered directly by the battery pack in most battery-operated applications for greater efficiency. The output voltage can be adjusted to -40V by using two external resistors. The SC16C654BIEC utilizes a pulse frequency modulation scheme to maintain high efficiency conversion under wide input voltage ranges. Its quiescent current is about 100µA and can be reduced to 8µA in shutdown mode. With a switching frequency range of 100kHz to 320kHz, this model is ideal for battery-powered portable equipment such as notebook and palmtop computers.
