Beschreibung

BD8303MUV is ROHM’s high efficiency step-up/step-down switching regulator IC. It produces output of 3.3V / 5V from 1 cell of lithium battery, 4 batteries, or 2 cells of Li batteries with just one inductor. This IC uses an original step-up/step-down drive system and provides a higher efficient power supply than conventional SEPIC-system or H-bridge system switching regulators.

Eigenschaften

  • Highly-Efficient Step-Up/Step-Down DC/DCConverter Implemented with Just One Inductor
  • Supports High-Current Applications with ExternalN-Channel FET
  • Incorporates a Soft-Start Function
  • Incorporates a Timer-Latch System with ShortCircuit Protection Function

Typische Anwendungen

  • Portable DVDs player, Laptop PCs
  • DVC (Digital Video Camera), Single-Lens Reflex Cameras
