ACT4088 Datasheet 1.4mhz Step-down DC/dc Converter

Manufacturer: Active-Semi

Overview: Rev PrA, 24-Jul-07 Advanced Product Information – All Information Subject to Change ACT4088 28V, 1.5A, 1.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General 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.

Optimized for use with ceramic input and output capacitors, the ACT4088 provides a very compact 1.5A power supply for space constrained mobile and consumer applications.

Key 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.
