Beschreibung
The ISL81401EVAL1Z evaluation board (shown in Figure 5 on page 8) features the ISL81401, a 40V high voltagesynchronous buck-boost controller that offers external soft-start, independent enable functions and integratesUV/OV/OC/OT protection. A programmable switching frequency ranging from 100kHz to 600kHz helps to optimizeinductor size while the strong gate driver delivers up to 20A for the buck-boost output.
Eigenschaften
- Wide input range: 6V to 40V
- Bi-directional 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
- Back biased from output to improve efficiency
Typische Anwendungen
- Medical equipment
- Redundant power supplies
