SC1630 - LOW VOLTAGE MULTI-MODE DC-DC CONVERTER

Description

The SC1630 is a DC-DC converter designed to drive an external power switch for more flexibility, especially in higher voltage and larger power applications.

Typically six components are required to set up a step-up configuration easily achieving an efficiency beyond 80%.

Features

  • Default +5V output voltage.
  • Adjustable output voltage with two resistors.
  • Power-saving shutdown mode (7µA typical).
  • 120kHz switching rate.
  • On-chip low battery detector BLOCK.

LOW VOLTAGE MULTI-MODE DC-DC CONVERTER January 30, 1998 SC1630 TEL:805-498-2111 FAX:805-498-3804 WEB:http://www.semtech.com DESCRIPTION The SC1630 is a DC-DC converter designed to drive an external power switch for more flexibility, especially in higher voltage and larger power applications. Typically six components are required to set up a step-up configuration easily achieving an efficiency beyond 80%. A few more components are required to set up a step down configuration delivering 4A load current with 83% typical efficiency, 86% at 2A load, and 300µA quiescent current. The output voltage can be internally set to 5V or externally set to an arbitrary value below breakdown voltage of the power switch. Logic-controlled shutdown mode is provided for power-saving.
