Renesas | ISL81401FRZ-T7A

Renesas Electronics has announced an innovative new family of bi-directional four-switch synchronous buck-boost controllers.

The ISL81601 and ISL81401 are bi-directional buck-boost power controllers. They accept an input from a battery power supply. A battery’s voltage declines as the battery loses charge, so a buck-boost controller can maintain a steady output voltage above or below the input from the battery

These buck-boost controllers are for use in systems running from large battery power supplies, such as battery back-up systems for industrial equipment or automotive products

Applications: 

• Battery back-up power supplies
• USB Type-C™ power supplies and chargers
• Battery-powered industrial applications
• Aftermarket automotive equipment
• Redundant power supplies
• Robots and drones
• Medical equipment
• Security and surveillance equipment

Features: 

  Programmable frequency range: 100kHz to 600kHz
 MOSFET drivers with adaptive shoot-through protection
 Light-load efficiency mode
 2.7μA shut-down current
 Frequency dithering for lower EMI in ISL81601 and ISL81401
 Over-voltage, under-voltage, over-current, over-temperature and short-circuit protection

Benefits:

The Renesas devices achieve very high efficiency to help extend the run-time of the battery between charges
