RT2862A

3A, 36V, Synchronous Step-Down Converter

General Description

Features

^z4.5V to 36V Input Voltage Range

The RT2862A is a high efficiency, current-mode

synchronous step-downDC/DC converter that can deliver

up to 3A output current over a wide input voltage range

from 4.5V to 36V. The device integrates 105mΩ high-side

and 80mΩ low-side MOSFETs to achieve high conversion

efficiency. The current-mode control architecture supports

fast transient response and simple external compensation.

^z3A Output Current

^zInternal N-MOSFETs

^zCurrent Mode Control

^zFrequency Operation : 300kHz to 1MHz

^zAdjustable Output Voltage from 0.8V to 30V

^zHigh Efficiency Up to 95%

^zStable with Low ESR Ceramic Output Capacitors

^zCycle-by-Cycle Current Limit

^zInput Under-Voltage Lockout

^zOutput Under-Voltage Protection

^zThermal Shutdown

A cycle-by-cycle current limit function provides protection

against shorted output and an internal soft-start eliminates

input current surge during start-up. The RT2862A provides

complete protection functions such as input under-voltage

lockout, output under-voltage protection, over-current

protection and thermal shutdown.

z Power Saving at Light Load

The RT2862Ais available in the thermal enhanced SOP-8

(Exposed Pad) package.

Applications

z Point of Load Regulator in Distributed Power Systems
