Page Contents:   [ Featured Products | Datasheets | Application Notes | Buy Now ]

The AME5172 is a high-efficiency, current mode, synchronous PWM boost DC-DC converter with fixed 3.3V output voltage for system applications powered by single or double cell NiMH or Alkaline battery pack.

Built-in 0.35W NMOS switch and 0.45W PMOS synchronous rectification significantly improves efficiency and reduces external component count. High switching frequency (at 1.2MHz) allows easy filtering and faster loop performance.

AME5172 uses a very small SOT-25 package which allows the size of the PC board area to be very small.

 

FEATURES PWM control with 1.2MHz fixed frequency Up to 92% efficiency 0.85V low start-up input voltage Internal synchronous rectifier Fixed 3.3V output voltage options 0.8A, 0.35 power MOSFET 1µA shutdown current SOT-25 package Standard ambient temperature range -40 to +85°C

APPLICATIONS Handheld devices Cordless keyboards and mice Digital cameras Portable applications MP3 players LCD bias power Wireless handsets
