Wide Input Voltage Range 2.5V to 21V
Wide Output Voltage Range 0.6V to 12V
Continuous 14A Load Capability
300kHz High Frequency Operation
Programmable Over-Current Protection
Programmable PGood Output
Hiccup Current Limit
The IR3820A SupIRBuckTM is an easy-to-use,
fully integrated and highly efficient DC/DC
regulator. The onboard switching controller and
MOSFETs make the IR3820A a space-efficient
solution, providing accurate power delivery for
low output voltage applications.
Precision Reference Voltage (0.6V)
Programmable Soft-Start
The IR3820A operates from a 4.5V to 14V input
supply and generates an output voltage
adjustable from 0.6V to 0.75*Vin at loads up to
14A.
Pre-Bias Start-up
Thermal Protection
Thermally Enhanced Package
Small Size 5mmx6mm QFN
Pb-Free (RoHS Compliant)
A versatile regulator offering programmability of
startup time, power good threshold and current
limit, the IR3820A’s fixed 300kHz switching
frequency allows the use of small external
components.
