SC1631 - LOW VOLTAGE STEP-UP DC-DC CONVERTER

Datasheet Summary

Description

The SC1631 is a high efficiency step up DC-DC converter.

Only four external components are required to deliver a fixed voltage of 3V, 3.3V, or 5V.

Efficiency beyond 87% can be easily achieved at 100mA load with 2.2V to 3V input voltages.

Features

  • High efficiency 90%.
  • Power-saving shutdown mode (7µA typical).
  • Internal 2A switch.
  • 120kHz switching rate.
  • Adjustable switch current limit.
  • On-chip low battery detector.

LOW VOLTAGE STEP-UP DC-DC CONVERTER January 29, 1998 SC1631 TEL:805-498-2111 FAX:805-498-3804 WEB:http://www.semtech.com DESCRIPTION The SC1631 is a high efficiency step up DC-DC converter. Only four external components are required to deliver a fixed voltage of 3V, 3.3V, or 5V. Efficiency beyond 87% can be easily achieved at 100mA load with 2.2V to 3V input voltages. A logic-controlled shutdown mode is provided for power saving. Switch current limit can be programmed with a resistor. The low battery detector can be configured as a linear regulator or a burst mode controller providing extremely low supply current operation. A switching rate of 120kHz reduces the inductor size inductors of 25µH to 50µH are recommended for most applications.
