Dual 1.3MHz, 800mA Synchronous Step-Down Converter

The APW7139 consists of two independent 1.3MHz constant frequency, current mode, and PWM step-down converters. Each converter integrates a main switch with a synchronous rectifier for high efficiency without an external Schottky diode. The APW7139 is ideal for powering portable equipment that runs f

33/4 Digit, Autoranging Multimeter

Description The Intersil ICL7139 and ICL7149 are high performance, low power, auto-ranging digital multimeter lCs. Unlike other autoranging multimeter ICs, the ICL7139 and ICL7149 always display the result of a conversion on the correct range. There is no “range hunting” noticeable in the display
