XR76203 / XR76205 / XR76208  
40V 3A/5A/8A Synchronous  
Step Down COT Regulator  
FEATURES  
General Description  
Controller, drivers, bootstrap diode and  
MOSFETs integrated in one package  
The XR76203, XR76205 and XR76208 are synchronous step-down  
regulators combining the controller, drivers, bootstrap diode and  
MOSFETs in a single package for point-of-load supplies. The XR76203,  
XR76205 and XR76208 have load current ratings of 3A, 5A and 8A  
respectively. A wide 5V to 40V input voltage range allows for single  
supply operation from industry standard 24V 10%, 18V-36V, and  
rectified 18VAC and 24VAC rails.  
3A, 5A and 8A Step Down Regulators  
Wide 5V to 40V Input Voltage Range  
≥0.6V 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  
CCM/DCM for high efficiency at light-load  
CCM for constant frequency at light-load  
With a proprietary emulated current mode Constant On-Time (COT)  
control scheme, the XR76203, XR76205 and XR76208 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  
0.07% load and 0.15% 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.  
Programmable Hiccup Current Limit with  
Thermal Compensation  
Precision Enable and Power Good flag  
Programmable Soft-start  
30-pin 5x5mm QFN package  
A host of protection features, including over-current, over-temperature,  
short-circuit and UVLO, helps achieve safe operation under abnormal  
operating conditions.  
APPLICATIONS  
Distributed Power Architecture  
Point-of-Load Converters  
Power Supply Modules  
The XR76203/5/8 are available in a RoHS-compliant, green/halogen-free  
space-saving QFN 5x5mm package.
