SC1408 - LOW VOLTAGE/ BOOST DC-DC CONTROLLER

General Description

The SC1408 is a low voltage boost controller that operates from a 1.8V to 16.5V input range.

A shutdown pin allows the user to turn the controller off reducing supply current to less than 2µA typical.

Output voltage can be preset to 5V or is adjustable from 3V to 16.5V with a resistor divider.

Key Features

  • = 1.8V to 16.5V input range.
  • = Up to 10W output power.
  • = Preset 5V or adjustable output.
  • = Up to 300kHz switching frequency.
  • = 10µA max shutdown current.
  • = Industrial temperature range.
  • = SO-8 or MSOP-8 package.

LOW VOLTAGE, BOOST DC-DC CONTROLLER August 22, 2000 SC1408 TEL:805-498-2111 FAX:805-498-3804 WEB:http://www.semtech.com DESCRIPTION The SC1408 is a low voltage boost controller that operates from a 1.8V to 16.5V input range. A shutdown pin allows the user to turn the controller off reducing supply current to less than 2µA typical. Output voltage can be preset to 5V or is adjustable from 3V to 16.5V with a resistor divider. The controller changes frequency in low load conditions to improve efficiency. The SC1408 was designed for two cell Alkaline or single cell Lithium Ion battery applications. With the proper external components it can be used as a boost converter or a buck/boost converter. A current sense is implemented with an external resistor that is not in the load current path.
