RT6160B

Low Quiescent, High Efficiency 3A Buck-Boost Converter

with I²C Interface

Features

General Description

⚫ Automatic Seamless Mode Transition with Real

Buck, Buck-Boost and Boost Operation

⚫ Input Voltage Range : 2.2V to 5.5V

⚫ Output Voltage Range : 2.025V to 5.2V with

Digitally Programmable (25mV/steps)

⚫ Default Output Voltage Setting :

The RT6160B is a high-efficiency, single inductor,

Advanced Constant On-Time (ACOT ) monolithic

synchronous Buck-Boost converter that can deliver up

to 3A output current from 2.2V to 5.5V and well regulate

to the digitally programmable output voltage from

2.025V to 5.2V, which is suitable for wide input supply

range applications, regardless of input voltage is lower,

 V

= 3.3V at VSEL = L

= 3.85V at VSEL = H

control architecture features outstanding

OUT

line/load transient response, seamless transition

between buck and boost modes, provides stable

operation with small ceramic output capacitors and

without complicated external compensation.

 Up to 3A for V ≥ 3V, V

= 5V

OUT

 Up to 2A for V ≥ 3V, V

⚫ Up to 95% Efficiency (V = 3.8V, V

= 3.3V,

OUT

= 1A)

LOAD

The RT6160B features I C interface, which allows

⚫ 1A Non-Switching Low Quiescent Current

programmable output voltage, ultra-sonic mode control,

soft-start slew-rate adjusted and device status

monitoring. The target output voltage can also be

switched through external VSEL pin to perform

dynamically-voltage-scaling (DVS), and the ramp-up

slew-rate and ramp mode of DVS can also be set by

setting the related registers.

⚫ I C Interface (Up to 1MHz)

⚫ Allows Dynamically-Voltage-Scaling Control

⚫ Automatic PFM Mode and Forced PWM Mode

Selection

⚫ Ultra-Sonic Mode Operation

⚫ OCP, UVLO, OTP, OVP, UVP Protected Function

for Robustness

The RT6160B operates in automatic PFM and typical

2A low quiescent current design that maintains high

efficiency during light load operation. At higher loads,

the device automatically switches to a 2.2MHz fixed

frequency control, which is easily smoothed-out he

switching ripple voltage by small package filtering

Applications

⚫ Smartphones and Tablets

⚫ Portable Devices

⚫ Wearable Devices

elements. And the integrated low R

power

DS(ON)

⚫ System Pre-Regulators

⚫ Point-of-Load Regulators

⚫ Wifi Module

MOSFETs features excellent efficiency during heavy

load conditions. In shutdown mode, the supply current

is typically 0.1A, excellent in reducing power

consumption. PFM mode can be disabled if fixed

frequency is desired. The RT6160B is available in a

small WL-CSP-15B 1.4x2.3 (BSC) package.
