SC16C2550BIB48 128 - Brand New NXP Semiconductors UARTs (Universal Asynchronous Receiver Transmitter)
-
Description
The SC16C2550BIB48 128 is a UART (Universal Asynchronous Receiver Transmitter) electronic component model. It is designed for high performance inverting DC-DC converter and to drive an external power switch to generate programmable negative voltages. It is particularly suitable for LCD bias contrast application, where maximum efficiency of 90% can be achieved with low-cost PNP bipolar transistor drivers. With an input operation range of 4V to 24V, it can be powered directly by the battery pack in most battery-operated applications for greater efficiency. The output voltage can be scaled to -40V by two external resistors, and a pulse frequency modulation scheme is employed to maintain high efficiency conversion under wide input voltage ranges. The device has a small size switching component range of 100kHz to 320kHz, and is ideal for battery-powered portable equipment such as notebook and palmtop computers. It has a quiescent current of about 100µA and can be reduced to 8µA in shutdown mode.
