YINGHUA UC2845AD8TR Switch controller SOIC-8 semiconductor

Switch controller IC in SOIC-8

The YINGHUA UC2845AD8TR is a current-mode PWM controller designed for offline and DC-to-DC converter circuits. It integrates a trimmed oscillator, undervoltage lockout, and a high-current totem-pole output in an 8-pin surface-mount package. Engineers select this device for cost-sensitive switch-mode power supply designs.

Suits new power-supply layouts

This part fits engineers laying out fresh SMPS boards who need a proven 8-pin controller with standard pinout. Designs requiring extended temperature range, higher switching frequency, or a different package style should evaluate alternative controllers.

SOIC-8 package constraint

The SOIC-8 footprint fixes the board layout and limits the available pin count to eight. Verify that the schematic and PCB land pattern match this package before committing to production.
