HT7727A, HT7730A, HT7733A, HT7750A Datasheet

The HT7750A, HT7727A, HT7730A, HT7733A, ICs are a set of PFM step-up DC to DC converters with high efficiency and low ripple. The series feature extremely low start-up voltage and high output voltage accuracy. They require only three external components to provide a fixed output voltage of 2.7V, 3V, 3.3V or 5V.

The HT7727A, HT7730A, HT7733A, HT7750A ICs consist of an oscillator, a PFM control circuit, a driver transistor, a reference voltage unit and a high speed comparator.
