What are the key features of UCC25705DG4?

High switching frequency up to 4000kHz enabling use of smaller passive components and compact converter designs
Voltage-mode PWM control for straightforward loop compensation and stable regulation across load conditions
Input voltage range from 9V to 15V ideal for 12V bus-powered power supply applications
20mA output drive current in compact 8-pin SOIC package for space-efficient PCB layouts

What is UCC25705DG4 used for?

The UCC25705DG4 is used in high-frequency switch-mode power supplies where compact magnetics and small passive components are required, such as point-of-load converters, isolated DC-DC modules, and telecom power stages. Its voltage-mode PWM control simplifies the error amplifier compensation network while the 4MHz switching capability significantly reduces transformer and inductor size. It is well suited for embedded systems, industrial automation, and communications equipment powered from 9V to 15V input rails.

Frequently Asked Questions

Which input rail conditions should be checked for UCC25705DG4?

UCC25705DG4 is specified for a 9 V to 15 V input range, so power-supply designers should confirm startup, bias, and transient limits around that rail.

How much switching-speed margin does this PWM controller offer?

The controller supports operation up to 4000 kHz, allowing compact magnetic components when the wider converter design can tolerate the related switching losses and layout demands.

For PCB assembly, how should the package be treated during qualification?

This ordering code is housed in an 8-pin SOIC surface-mount package, so buyers should verify footprint, reel format, and second-source constraints before production approval.
