General Description

The HT7627 DC/DC converter with built in voltage detector is a high performance CMOS IC, suitable for use in battery-powered system application with low noise and low supply current. The HT7627 consists of two major parts, one is DC/DC converter and the other is voltage detector. The DC/DC converter part consists of reference voltage source, error amplifier, control transistor, oscillation circuit and output voltage setting resistor.

Features

• High output voltage accuracy: 5

• Low ripple and low noise

• Low start-up voltage (when the output current is 1mA): 0.95V

• Low current consumption: 14μA with 1.5V input (typ.)

• Fixed output voltage: 2.7V

• Built-in 2.1V (typ.) voltage detector

• 8-pin SOP package

Applications

• Pager

• RF Mouse/Keyboard
