Product Summary

The ht7750a is a PFM step-up DC/DC converter with high efficiency and low ripple. The ht7750a features 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, 3.0V, 3.3V or 5.0V. CMOS technology ensures ultra low supply current and makes them ideal for battery-operated applications powered from one or more cells. The ht7750a consists of an oscillator, a PFM control circuit, a driver transistor, a reference voltage unit, and a high speed comparator. The ht7750a employs pulse frequency modulation (PFM) for minimum supply current and ripple at light output loading. These devices are available in space saving TO-92, SOT-89, SOT-23 and SOT-25 packages. For SOT-25 package, it also build-in a chip enable function to reduce power consumption during shutdown mode.
