Description
The HM1470 is a high frequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs. It offers a very compact solution to achieve a 2A continuous output current over a wide input supply range, with excellent load and line regulation. The HM1470 requires a minimal number of readily available, external components and is available in a space saving SOT23-6 package.

Features
• Wide 4V to 18V Operating Input Range
• 2A Continuous Output Current
• No Schottky Diode Required
• 500KHz Frequency Operation
• Built-in Over Current Limit
• Built-in Over Voltage Protection
• Internal Soft start
• Output Adjustable from 0.8V
• Integrated internal compensation
• Short Protection with Hiccup-Mode
• Thermal Shutdown
• Available in SOT23-6 Package
• -40°C to +85°C Temperature Range

Applications
• Digital Set-top Box (STB)
• Tablet Personal Computer (Pad)
• Flat-Panel Television and Monitor
• Wi-Fi Router / AP
• Digital Video Recorder (DVR)
• Portable Media Player (PMP)
• Cable Modem / XDSL
