LINEAR INTEGRATED CIRCUIT
3A, 23V, 340KHZ
SYNCHRONOUS RECTIFIED
STEP-DOWN CONVERTER
„ DESCRIPTION
The UTC P1484A is a synchronous buck regulator. The
device provides3A of continuous load current over a wide input
voltage of 5V~23V. Current mode control provides fast transient
response and cycle-bycycle current limit. An adjustable soft-start
prevents inrush current at turn-on
The UTC P1484A 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
* 3A Output Current
* Wide 6V~23V Operating Input Range
* Integrated Power MOSFET Switches
* Programmable Soft-Start
* Stable with Low ESR Ceramic Output Capacitors
* Fixed 340KHz Frequency
* Cycle-by-Cycle Over Current Protection
