40V SYNCHRONOUS BUCK CONTROLLER WITH 2CH CC/CV

DESCRIPTION

The UTC UCC40702 is a synchronous buck controller. The

device need externals high side and external low side power

MOSFETs, and provides 5A of continuous load current and a wide

input voltage of 8V to 40V. Current mode control provides fast

transient response and cycle-by-cycle current limit. An internal

soft-start prevents inrush current at turn-on.

FEATURES

* Wide 8V ~ 40V Operating Input Range

* Externals high side and low side Power MOSFET Switches

* Output Adjustable from VFB(1.00V±2%) to 16V

* Up to 95% Efficiency

* Internal Soft-Start and Fixed 160KHz Frequency

* Duty on ratio : 0% ~ 91% PWM control

* Cycle-by-Cycle Over Current Protection

* Input Under/Over Voltage Lockout
