1.6 MHz Boost Converter With 30V Internal FET Switch in SOT-23

 

Recommended alternative parts

  • LM27313-Q1  - The device has SIMILAR FUNCTIONALITY but is not functionally equivalent to the compared device. 
  • TLV61046A  -  28-V Output Voltage Boost Converter with Power Diode and Isolation Switch

Description

The LM27313/-Q1 switching regulator is a current-mode boost converter with a fixed operating frequency of 1.6 MHz.

The use of the SOT-23 package, made possible by the minimal losses of the 800-mA switch, and the small inductors and capacitors result in extremely high power density. The 30-V internal switch makes these solutions perfect for boosting to voltages of 5 V to 28 V.

This device has a logic-level shutdown pin that can be used to reduce quiescent current and extend battery life.

Protection is provided through cycle-by-cycle current limiting and thermal shutdown. Internal compensation simplifies design and reduces component count.
