Description
HM1482C is a monolithic 30V, 2.5A step-down switching regulator. HM1482C integrates a 36V 86mΩ high side and a 36V, 74mΩ low side MOSFETs to provide 2.5A continuous load current over a 6.5V to 30V wide operating input voltage with input over voltage protection. Peak current mode control provides fast transient responses and cycle-by-cycle current limiting. Programmable soft-start prevents inrush current at power-up.

Features
● 2.5A continuous output current capability
● 6.5V to 30V wide operating input range with 33V input Over Voltage Protection
● Integrated 36V, 86mΩ high side and 36V, 74mΩ low side power MOSFET switches
● Up to 95% efficiency
● Programmable Soft-Start limits the inrush current at turn-on
● Stable with Low ESR Ceramic Output Capacitors
● Fixed 300KHz Switching Frequency
● Input Under-Voltage Lockout. Output Over-Voltage Protection
● Over-Temperature Protection
● Thermally Enhanced ESOP-8 Package

Applications
● Set-Top-Box
● Televisions
● DVD, LCD Displays
● OLPC, Netbook
● Datacom, XDSL modems
● Distributed Power Systems
● USB car charger
● Portable charging device
● General purpose
