What are the key features of UC2825ANG4?
- Dual-mode current/voltage-mode PWM control with up to 1 MHz switching frequency for compact, high-efficiency switch-mode power supply designs
- Wide 8.8 V to 22 V input voltage range accommodating 12 V and 15 V bus supplies common in industrial and telecom power systems
- 200 mA gate drive output current capability enables direct drive of power MOSFETs and IGBTs without external gate driver buffers in medium-power applications
- 16-pin DIP through-hole package supports both breadboard prototyping and wave-soldered production assemblies, ideal for industrial and legacy system designs
What is UC2825ANG4 used for?
The UC2825ANG4 is used as the primary control IC in half-bridge, full-bridge, and push-pull switch-mode power supplies for industrial equipment, telecommunications rectifiers, and DC-DC converters operating from 12 V to 20 V input rails. Its 1 MHz capability reduces the size of magnetics and filter capacitors, enabling compact power module designs. The device is also applied in motor drive gate signal generation and battery charger controllers where flexible current-mode feedback loops simplify compensation and improve transient response.

Frequently Asked Questions
What control modes does the UC2825ANG4 support?
The UC2825ANG4 supports both current-mode and voltage-mode PWM control. Current-mode control uses inductor current as a feedback signal to the inner control loop, providing inherent cycle-by-cycle current limiting and improved line rejection. The device can also be configured in pure voltage-mode control by connecting appropriate external components.
What is the maximum switching frequency of the UC2825ANG4?
The UC2825ANG4 supports switching frequencies up to 1 MHz. Operating at high frequency reduces the required inductance and capacitance values in the power stage, enabling physically smaller magnetics and filter components that lower the overall size and cost of the power supply design.
What is the input voltage range of the UC2825ANG4?
The UC2825ANG4 operates from an input supply voltage range of 8.8 V minimum to 22 V maximum, with a nominal operating voltage of 12 V. This range covers standard 12 V and 15 V bus supplies found in industrial equipment, telecommunications power systems, and laboratory bench power supplies.
What gate drive capability does the UC2825ANG4 provide?
The UC2825ANG4 provides a 2 V output gate drive rail with 200 mA peak output current capability. This output can directly drive the gates of small to medium power MOSFETs and IGBTs in the power stage without requiring a separate gate driver IC, reducing component count in lower-power converter designs.
What package does the UC2825ANG4 use and is it suitable for prototyping?
The UC2825ANG4 is available in a 16-pin DIP (Dual In-line Package) through-hole package. DIP packages are directly compatible with solderless breadboards and standard IC sockets, making them ideal for prototyping and development. The through-hole format also suits wave-soldering in production environments for industrial applications requiring robust mechanical solder joints.
