TPS56623x 3-V to 18-V Input, 6-A Synchronous Step-Down Voltage Regulator

1 Features

3 Description

•

Configured for rugged applications

– Input voltage range: 3 V to 18 V

– Output voltage range: 0.6 V to 7 V

– 6-A continuous output current

– 0.6-V ±1% reference voltage (25°C)

– 98% maximum duty cycle

– 600-kHz switching frequency

– Non-latched for OC, OV, UV, and OT

protections

The TPS56623x are simple, easy to use, high-

efficiency, 6-A synchronous buck converters in a QFN

9-pin 1.5-mm x 2.0-mm package.

The devices operate with wider supply input voltage

ranging from 3 V to 18 V. The D-CAP3^™control mode

was adopted to provide a fast transient response,

good line and load regulation, no requirement for

external compensation, and to support low-ESR

output capacitors.

– Built-in output discharge function

Numerous pin-compatible options

– TPS566231 and TPS566238 with SS pin for

adjustable soft-start time

– TPS566231P and TPS566238P with PG pin for

power good indicator

The TPS566231 and TPS566231P operate in Eco-

Mode^™for high efficiency during light load operation,

and are designed with ULQ^™(Ultra Low Quiescent)

feature, achieving 50-uA quiescent current to enable

long battery life in low-power applications. The

TPS566238 and TPS566238P operate in continuous

current mode, which maintains lower output ripple

during all load conditions.

•

– TPS566231 and TPS566231P for auto-skip

mode

The TPS566231 and TPS566238 soft-start time can

be adjusted through the SS pin. The TPS566231P

and TPS566238P indicate power good through the

PG pin.

– TPS566238 and TPS566238P for continuous

current mode

Small solution size and ease of use

– Integrated power MOSFET with R_DS(on)20.8

mΩ and 10.6 mΩ

– D-CAP3^™architecture control for fast transient

response and internal compensation

– 1.5-mm × 2.0-mm HotRod^™QFN package

– Create a custom design with the WEBENCH®

Power Designer

•

The TPS56623x can support up to 98% duty cycle

operation, and integrate complete protection through

OVP, OCP, UVLO, OTP, and UVP with hiccup. They

are each available in a 9-pin 1.5-mm x 2.0-mm

HotRod^™package and the junction temperature is

specified from -40°C to 125°C.
