Fonctionnalités et applications
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
