Renesas ISL81801DEMO1Z | Demoboard ISL81801DEMO1Z
80V Bidirectional 4-Switch Synchronous Buck-Boost Controller
Overview
| Topology | Buck-Boost Converter |
| Input voltage | 32-80 V |
| Switching frequency | 100-600 kHz |
| Output 1 | 48 V / 10 A |
| IC revision | 1 |
Description
The ISL81801DEMO1Z demonstration board (shown in Figure 8) features the ISL81801, a 80V high voltage synchronous buck-boost controller that provides external soft-start, independent enable functions, and integrates UV/OV/OC/OT protection. Programmable switching frequency ranging from 100kHz to 600kHz helps to optimize the inductor size while the strong gate driver delivers up to 20A for the buck-boost output.
Features
- Wide input range: 32V to 80V
- Bidirectional operation
- High light-load efficiency in pulse skipping DEM operation
- Programmable soft-start
- Optional DEM/PWM operation
- Optional CC/HICCUP OCP protection
- Supports prebias output with soft-start
- PGOOD indicator
- OVP, OTP, and UVP protection
- Parallelable operation
Typical applications
- Medical equipment
- Robots and drones
- Redundant power supplies
- Security surveillance
- Battery backup, UPS/storage systems, Battery powered industrial applications, Renewable energy
- Building and industrial automation
- Aftermarket automotive
