FEATURES

ꢀ■

Automotive AEC-Q100 Qualified

Temperature Grade 1: -40°C to 125°C

HBM ESD Class Level 2

CDM ESD Class Level C4B

ꢀ■

Controller, drivers, bootstrap diode and

MOSFETs integrated in one package

ꢀ■

3A, 5A and 8A step-down regulators

5.5V to 40V operating range

3V to 40V PV_INwith 5V bias

≥0.6V adjustable output voltage

ꢀ■

Patented COT control

Programmable 200ns to 2μs on-time

Constant 100kHz to 800kHz frequency

The AEC-Q100 qualified XR76203-Q, XR76205-Q and XR76208-Q are

synchronous step-down regulators combining the controller, drivers,

bootstrap diode and MOSFETs in a single package for point-of-load

supplies well suited for automotive applications. The XR76203-Q,

XR76205-Q and XR76208-Q have load current ratings of 3A, 5A and

8A, respectively. A wide 5.5V to 40V input voltage range allows for

single supply operation from industry standard 24V 10ꢀ, 18V to 36V

and rectified 18VAC and 24VAC rails and 12V battery systems requiring

inherent load dump protection.

ꢀ■

Selectable CCM or CCM/DCM

CCM/DCM for high efficiency at light load

CCM for constant frequency at light load

ꢀ■

Programmable hiccup current limit with thermal

compensation

ꢀ■

Precision enable and Power Good flag

Programmable soft-start

Common scalable footprint 30-pin, 5mm x

5mm QFN package with wettable flanks

With a proprietary emulated current mode Constant On-Time (COT)

control scheme, the XR76203-Q, XR76205-Q and XR76208-Q provide

extremely fast line and load transient response using ceramic output

capacitors. They require no loop compensation, simplifying circuit

implementation and reducing overall component count. The control

loop also provides 0.07ꢀ load and 0.15ꢀ line regulation and maintains

constant operating frequency. A selectable power saving mode allows

the user to operate in Discontinuous Conduction Mode (DCM) at light

current loads thereby significantly increasing the converter efficiency.

A host of protection features, including over-current, over temperature,

short-circuit and UVLO, helps achieve safe operation under abnormal

operating conditions. These 40V regulators deliver power to a wide

range of automotive, industrial and military equipment.

BENEFITS

ꢀ■

Excellent line and load regulation compared to

standard COT

ꢀ■

Stable with ceramic output capacitors

ꢀ■

No compensation required

ꢀ■

Fast transient response with ability to work with

low ESR capacitors

APPLICATIONS

ꢀ■

Automotive systems

Infotainment head units

Advanced Driver Assistance Systems (ADAS)

ꢀ■

Distributed power architecture

ꢀ■

Point-of-Load (POL) converters

ꢀ■

Power supply modules

ꢀ■

FPGA, DSP and processor supplies

ꢀ■

Industrial and military applications

Power modules, point-of-load regulators, system controls,

LED lighting and Universal PMIC solutions simplify power

and system architecture in a wide variety of end markets
