RT6158H

High Efficiency, Low Quiescent, 3A Buck-Boost Converter

General Description

Features

^Input Voltage Range : 2.5V to 5.5V

^Adjustable Output Voltage : 2.1V to 5.2V by External

Divided Resistors

The RT6158H converter is a high efficiency single inductor

converter which can operate with wide input voltage such

as battery which is higher or lower than the output voltage

and it can supply the load current up to 3A. The maximum

peak current in the switches is limited to a typical value of

6.5A. Feedback loop is internally compensated for both

Buck and Boost operation and it provides seamless

transition between Buck and Boost modes and optimal

transient response. The Buck-Boost operates at 1.5MHz

typical switching frequency in full synchronous operation.

^Up to 3A Maximum Load Capability for V_IN= 3V,

V_OUT= 3.5V

^Up to 96% Efficiency

^OCP, OVP, OTP Protected Function

^2MHz Switching Frequency

^5μA Non-Switching Low Quiescent Maximizes

Light Load Efficiency

^Forced PWM and Automatic PFM/PWM Mode

Selection

The RT6158H operates in Pulse Frequency Modulation

(PFM) mode for increasing efficiency during low power

RF transmission modes. The PFM mode can be disabled,

forcing the RT6158H to operate at a fixed switching

frequency operation at 2MHz. The RT6158H can also be

synchronized with external frequency from 2.2MHz to

2.6MHz. The RT6158H output voltage is programmable

using an external resistor divider; the output voltage range

is from 2.1V to 5.2V.
