Applications
Description
The IR3802 SupIRBuckTM is an easy-to-use, fully
integrated and highly efficient DC/DC regulator.
The onboard switching controller and MOSFETs
make the IR3802 a space-efficient solution,
providing accurate power delivery for low output
voltage applications.
The IR3802 operates from a single 4.5V to 14V
input supply and generates an output voltage
adjustable from 0.6V to 0.75*Vin at loads up to 4A.
A versatile regulator offering programmability of
startup time, power good threshold and current
limit, the IR3802’s fixed 600kHz switching
frequency allows the use of small external
components.
• Game Consoles
• Set-top Boxes
• Graphics Cards
• LCD TVs
• Desktop PCs
• Distributed Point-of-Loads
• Embedded Systems
• Computing Peripheral Voltage Regulators
The IR3802 also features important protection
functions, such as Pre-Bias startup, hiccup
current limit and thermal shutdown to provide the
required system level security in the event of fault
conditions.
