Beschreibung
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.
Eigenschaften
- 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
Typische Anwendungen
