ACT4088US-T - 1.4MHz Step-Down DC/DC Converter

Download the ACT4088US-T datasheet PDF. This datasheet also covers the ACT4088 variant, as both devices belong to the same 1.4mhz step-down dc/dc converter family and are provided as variant models within a single manufacturer datasheet.

Description

The ACT4088 is a current-mode step-down DC/DC converter that supplies up to 1.5A into 5V from a 12V input.

1.4MHz switching frequency allows the use of tiny external components, and internal loop compensation provides simple, stable power supplies with a minimum of external components.

Features

  • Wide 4.5V to 28V Input Voltage Range.
  • 1.5A Output Current (12VIN to 5VOUT).
  • Output Adjustable Down to 0.81V.
  • 0.3Ω Internal Power MOSFET.
  • Up to 92% Efficiency.
  • Stable with Low ESR Ceramic Output Capacitors.
  • Fixed 1.4MHz Operating Frequency.
  • Internal Soft-Start Function.
  • Over Current Protection with Hiccup-Mode.
  • Thermal Shutdown.
  • Available in a SOT23-6 Package.
