RT6158A

High Efficiency, Low Quiescent, 2A Buck-Boost Converter

General Description

Features

^Input Voltage Range : 2.5V to 5V

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

Divided Resistors

The RT6158A converter is a high efficiency single inductor

converter which can operate with wide input voltage 2.5V

to 5V such as battery which is higher or lower than the

output voltage and it can supply the load current up to 2A.

The maximum peak current in the switches is limited to a

typical value of 4.5A. 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 2MHz typical switching frequency in full

synchronous operation.

^Up to 2A Maximum Load Capability for V_IN= 3V,

V_OUT= 3.5V

^Up to 96% Efficiency (V_IN= 4.2V, V_OUT= 3.5V, I_LOAD

0.5A)

^OCP, OVP, OTP, UVLO and SCP Function

^2MHz Switching Frequency

^5μA Non-Switching Low Quiescent Current

^Forced PWM and Automatic PFM/PWM Mode

Selection

The RT6158A operates in Pulse Frequency Modulation

(PFM) mode for increasing efficiency. The PFM mode can

be disabled, forcing the RT6158A to operate at a fixed

switching frequency operation at 2MHz. The RT6158Acan

also be synchronized with external frequency at MODE

pin from 2.2MHz to 2.6MHz. The RT6158A output voltage

is programmable using an external resistor divider; the

output voltage range is from 2.1V to 5.2V.

 Output Fast Discharge Function

 Automatic / Seamless Step Up and Step Down

Mode Transitions

 25-Ball WL-CSP Package
