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
