HT7750A

PFM Step-up DC/DC Converter
( TO92 Package 限用產品 公告日: 2018/12/18 生效日: 2019/03/18)
(TO92 Package 產品終止信息)

The HT7750A series is a set of PFM step-up DC/DC converter with high efficiency and low ripple. The series 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, 3.7V 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. They employ pulse frequency modulation (PFM) for minimum supply current and ripple at light output loading. These devices are available in space saving SOT89, SOT23 and SOT23-5 packages. For SOT23-5 package, it also build-in a chip enable function to reduce power consumption during shutdown mode.

 

  • Low start-up voltage: 0.7V (Typ.)
  • High efficiency: 85% (Typ.)
  • High output voltage accuracy: ±2.5%
  • Output voltage: 2.7V, 3.0V, 3.3V, 5.0V
  • Output current up to 200mA
  • Ultra low supply current IDD: 5μA (Typ.)
  • Low ripple and low noise
  • Low shutdown current: 0.5μA (Typ.)
  • 3-pin SOT89, 3-pin SOT23 and 5-pin SOT23 package
