SR2803

LINEAR INTEGRATED CIRCUIT

330KHZ, 3A SYNCHRONOUS

BUCK CONTROLLER

DESCRIPTION

The UTC SR2803 is a synchronous buck regulator. The device

provides 3A of continuous load current over a wide input voltage

of 4V~28V. Current mode control provides fast transient response

and cycle by cycle current limit. Integrates soft start, and

shutdown mode.

The UTC SR2803 can provide low-ripple power, high

efficiency, and perfect transient characteristics. The duty ratio

varies linearly from 0% to 92% in the PWM control. The error

amplifier circuit and soft-start circuit included in this device can

prevent overshoot at startup. An enable function, an over current

protect (OCP) function and short circuit protect (SCP) are also

build inside, and when OCP happens, the operation frequency

will be reduced.

FEATURES

* Input voltage varies from 4V ~ 28V

* Output voltage varies from 0.8V to V_CC

* Duty ratio varies from 0% to 92% PWM control

* With 330kHz typical oscillation frequency

* Thermal shutdown and SCP function and soft-start, current limit,

enable function

* Low ESR output capacitor(Multi-layer chip capacitor) application

* Halogen Free
