The UC3825DW is an enhanced double ended PWM controller designed for high frequency switched mode power supply applications. It offers practical operation switching frequencies up to 1MHz and features high current dual totem pole outputs capable of 1.5A peak current. The controller includes features such as 85% maximum duty cycle control, pulse-by-pulse current limiting, and soft start.
With a wide bandwidth error amplifier and fully latched logic with double pulse suppression, the UC3825DW is optimized for minimizing propagation delays. It operates within a temperature range of 0°C to 70°C and includes under-voltage lockout with hysteresis (9.2V/8.4V) and a low start-up current of 1.1mA. The device is available in a 16-pin SOIC (DW) package suitable for surface mounting.
This controller is compatible with both voltage and current mode topologies, making it versatile for various power supply designs. It is important to note that this part is not recommended for new designs.
