MPS MP1540DJ-LF-Z 1.3MHz, 18V Step-Up Converter

The MP1540 is a 5-pin thin TSOT23 current  mode step-up converter intended for small, low  power applications.

  • Brand:

    MPS
  • Product Details

DESCRIPTION  

The MP1540 is a 5-pin thin TSOT23 current  mode step-up converter intended for small, low  power applications. The MP1540 switches at  1.3MHz and allows the use of tiny, low cost  capacitors and inductors 2mm or less in height.  Internal soft-start results in small inrush current  and extends battery life. The MP1540 operates  from an input voltage as low as 2.5V and can  generate 12V at up to 200mA from a 5V  supply.  

The MP1540 includes under voltage lockout,  current limiting, and thermal overload  protection to prevent damage in the event of an  output overload. The MP1540 is available in a  small 5-pin TSOT23 package.
