HT7727S - 100mA PFM Synchronous Step-up DC/DC Converter

Download the HT7727S datasheet PDF. This datasheet also covers the HT7718S variant, as both devices belong to the same 100ma pfm synchronous step-up dc/dc converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The HT77xxS 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.

Key Features

  • Low start-up voltage: 0.7V (Typ. ).
  • High efficiency: 1.8V ≤ VOUT ≤ 2.2V upper 80%, 2.7V ≤ VOUT ≤ 5.0V upper 85% (Typ. ).
  • High output voltage accuracy: ±2.5%.
  • Output voltage: 1.8V, 2.2V, 2.7V, 3.0V, 3.3V, 3.7V, 5.0V.
  • Output current up to 100mA.
  • Ultra low supply current IDD: 4μA (Typ. ).
  • Low ripple and low noise.
  • Low shutdown current: 0.1μA (Typ. ).
  • TO92, SOT89, SOT23 and SOT23-5 package.
