RTQ2077S-QT

DC-DC Converters + LDO PMIC for Industrial/Automotive

Application

General Description

Features

^AEC-Q100 Grade 1 Qualified

The RTQ2077S is a highly-integrated, low-power high

performance PMIC (Power Management IC) for Industrial/

Automotive applications. The device includes one 400mA

high voltage synchronous step-downDC-DC converter and

one 200mAlow dropout LDO.All MOSFETs are integrated,

and compensation networks are built-in.

 −40°C to 125°C Operating Ambient Temperature

Range

^2.7V to 5.5V Input Voltage Range for LDO

^4.5V to 15V Input Voltage Range for HV-Step-Down

Regulator

^2MHz Switching Frequency

The RTQ2077S is an Automotive-Grade Product that is

AEC-Q100Grade 1 Qualified and provides fault condition

protections, including over-current protection, under-

voltage lockout, over-voltage protection and over-

temperature protection. The RTQ2077S is available in

WQFN-16L 3x3 package.

^Adjustable Output Voltage from 2.7V to 5V for HV-

Step-Down Regulator

^Adjustable Output Voltage from 1V to 3.6V for LDO

^Peak Current Mode Control

 Integrated 330mΩ /150mΩ MOSFETs

 Enable Control

 Power Good Indicator
