Power Supply Controllers, Monitors datasheet and documents for UC2845D8TRG4

UC2845D8TRG4

Power Supply Controllers, Monitors Overview

The UC2845D8TRG4 is a current-mode PWM controller manufactured by Texas Instruments, designed for DC-DC switching applications. It supports Boost, Flyback, and Forward topologies within an 8-pin SOIC package. The device operates with a maximum switching frequency of 500 kHz and delivers a peak output drive current of 1 A. It features a fixed maximum duty cycle of 50% and includes an internal 5 V reference voltage. The component functions within a supply voltage range of 10 V to 30 V and maintains reliable operation across an industrial temperature range from -40°C to +85°C.

Power Supply Controllers, Monitors Feature Summary

Implements current-mode control architecture for enhanced transient response and simplified compensation.

Power Supply Controllers, Monitors Applications

Boost converter designs
Flyback power supply implementations
Forward converter circuits

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's official documentation to confirm RoHS compliance status and lead-free manufacturing details. Ensure the ordering part number matches the exact package variant required for the target PCB footprint. Cross-reference the datasheet revision history to validate any recent design or packaging changes that may affect integration.

Power Supply Controllers, Monitors Selection Notes

Select this component when a 50% maximum duty cycle constraint aligns with the specific boost or forward topology requirements. The 1 A output driver capability suits moderate load applications without requiring external gate drivers. Verify that the 500 kHz switching frequency meets the desired trade-off between magnetic component size and switching losses for the target design.

Power Supply Controllers, Monitors Part Context

This part belongs to the UCx84x family of current-mode PWM controllers produced by Texas Instruments. It shares functional similarities with other variants in the series but is distinguished by its specific commercial temperature rating and package configuration. The device serves as a core control element in isolated and non-isolated power conversion systems.
