40V Synchronous Step Down COT Controller

FEATURES

General Description

 20A Capable Step Down Controller

 Wide 5.5V to 40V Input Voltage Range

 Integrated High Current 2A/3A Drivers

 0.6 to 30V Adjustable Output Voltage

 Proprietary Constant On-Time Control

 No Loop Compensation Required

 Stable Ceramic Output Capacitor Operation

 Programmable 200ns to 2μs On-Time

 Constant 100kHz to 800kHz Frequency

 Selectable CCM or CCM/DCM Operation

 Programmable Hiccup Current Limit with Ther-

mal Compensation

 Precision Enable and Power Good flag

 Programmable Soft-start

 Integrated Bootstrap diode

 16-pin QFN package

The XR75100 is a synchronous step-down controller for point-of load sup-

plies up to 20A. A wide 5.5V to 40V input voltage range allows for single

supply operation from industry standard 12V, 18V, and 24V DC and AC

rails.

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

trol scheme, the XR75100 provides extremely fast line and load transient

response using ceramic output capacitors. It requires no loop compensa-

tion hence simplifying circuit implementation and reducing overall compo-

nent count. The control loop also provides exceptional load and line

regulation and maintains constant operating frequency. A selectable

power saving mode allows the user to operate in discontinuous 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, help achieve safe operation under abnormal

operating conditions.

APPLICATIONS

The XR75100 is available in RoHS compliant, green/halogen free space-

saving 16-pin 3x3 QFN package.

 Networking and Communications

 Fast Transient Point-of-Loads

 Industrial and Medical Equipment

 Embedded High Power FPGA
