DESCRIPTION
The DS1050 is a programmable, 5-bit, pulse-width modulator featuring a 2-wire addressable controlled
interface. The DS1050 operates from power supplies ranging from 2.7V up to 5.5V. The PWM output
provides a signal that swings from 0V to V
CC
. The DS1050 requires a typical operating current of 50 A
and a programmable shutdown supply current of 1 A.
Four standard PWM output frequencies are offered and include 1kHz, 5kHz, 10kHz, and 25kHz. The
2-wire addressable interface allows operation of multiple devices on a single 2-wire bus and provides
compatibility with other Dallas Semiconductor 2-wire devices such as real-time clocks (RTCs), digital
thermometers, and digital potentiometers.
The device is ideal for low-cost LCD contrast and/or brightness control, power supply voltage
adjustment, and battery charging or current adjustment. The DS1050 is offered in standard integrated
circuit packaging including the 8-pin (150-mil) SOIC and space-saving 8-pin (118-mil) SOP.
