HT7730SA - 200mA PFM Synchronous Step-up DC/DC Converter

Download the HT7730SA datasheet PDF. This datasheet also covers the HT7727SA variant, as both devices belong to the same 200ma pfm synchronous step-up dc/dc converter family and are provided as variant models within a single manufacturer datasheet.

Description

The HT77xxSA devices are a high efficiency PFM synchronous step-up DC-DC converter series which are designed to operate with both wire wound chip power inductors and also with multi-layered chip power inductors.

Features

  • Low start-up voltage: 0.7V (Typ. ).
  • High efficiency: 2.7V ≤ VOUT ≤ 5.0V upper 90% (Typ. ).
  • High output voltage accuracy: ±2.5%.
  • Output voltage: 2.7V, 3.0V, 3.3V, 3.7V, 5.0V.
  • Output current up to 200mA.
  • Ultra low supply current IDD: 5μA (Typ. ).
  • Low ripple and low noise.
  • Low shutdown current: 0.1μA (Typ. ).
  • TO92, SOT89, SOT23 and SOT23-5 package.
