Product Description
Texas Instruments UC3825N is a 16-pin PDIP dual-channel current mode PWM controller, optimized for power management applications. Designed with a maximum switching frequency of 1000 kHz and capable of handling up to 125V supply voltage, it supports efficient PWM control with a supply current of only 4mA.
This PWM controller provides 5.2V output voltage and can deliver 1.5A output current across its two outputs. It features a maximum duty cycle of 85%, making it suitable for high-power switching power supplies.
The device comes in a through-hole mount 16-pin PDIP package measuring 19.3 mm in length, 6.35 mm in width, and 4.57 mm in height, designed for reliable PCB integration.
Its design incorporates flyback controller features with primary-side regulation technology which enhances power supply transient response and eliminates the need for optocouplers, simplifying power supply designs.
Operable across an industrial temperature range of 0°C to 70°C, the UC3825N controller is ideal for applications in industrial automation, power management ICs, and electronic instrumentation.
Dual 2-channel PWM outputs enable flexible power control configurations. Low supply current reduces energy consumption for efficient operation. Current mode PWM control improves regulation and transient response. Primary-side regulation simplifies control loops and reduces component count.
Robust operating temperature supports a variety of industrial environments.
Suitable for design engineers working in electronics and power supply manufacturing, Texas Instruments UC3825N facilitates high-performance switching power supply control, increasing efficiency and reliability for industrial and commercial systems.
