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. It consists of two major parts, one is DC/DC converter and the other is voltage detector. The DC/DC converter HT7627 part consists of reference voltage source, error amplifier, control transistor, oscillation circuit and output voltage setting resistor. The voltage detector part consists of a high-precision and low power consumption standard voltage source, a comparator, hysteresis circuit and an output driver. As external parts, a coil, a diode, and a capacitor are available for obtaining a constant output (2.7V) higher than the input voltage for the DC/DC converter part.
