The UC3625NG4 is a current-mode, synchronous buck controller designed to provide a cost-effective solution for high current, low voltage dc/dc applications. The device has been specifically designed for use in power supplies and battery-operated applications. It is widely used in a variety of motor drive, controller and power management applications.

The UC3625NG4 is an ideal solution for powering high current, low voltage dc/dc converters and general-purpose DC-DC converters. The device features on-chip voltage sequencing and sequencing options with up to four independent outputs. It also features an integrated PWM/PFM controller, a power-on reset, and a patented current limit circuit for improved efficiency. The device also features a wide operating temperature range and a temperature-compensated voltage reference. The integrated voltage reference and PWM/PFM circuit help to reduce the BOM cost and size of the design.

The UC3625NG4 includes a high-speed dual-output peak current-mode synchronous buck controller with an integrated PWM/PFM control circuit that is optimized for driving high current loads with low noise and fast transient response. The device has adjustable peak current-mode control with an internal voltage-mode current limit. With its on-chip low-dropout linear regulator and adjustable start voltage, the device allows the user to further reduce the size and cost of the power supply design.

The UC3625NG4 also includes an internal temperature-compensated voltage reference with built-in current limiting circuitry. This feature enables the user to more accurately set the protective overcurrent and overvoltage conditions by using the on-chip voltage reference and not an external voltage source. The device also features an adjustable external-clock divider for improved noise control and externally selectable overcurrent limiting. The integrated enable/disable control allows for both no-load and full-load shutdown.

The UC3625NG4 is the ideal device for a wide range of applications in the motor drive, controller and power management industry. Its high speed, low noise, and fast transient response make it suitable for high current handheld and automotive products. Its integrated PWM/PFM control circuit, adjustable start voltage, and temperature-compensated voltage reference make it ideal for low voltage power supplies. Its on-chip linear regulator and current limit circuitry allow for reduced BOM cost, and its external-clock divider and adjustable overcurrent limiting allow for improved noise control.
