| Switching frequency | 90-650 kHz |
| Output 1 | 12 V / 8 A |
| IC revision | 0.00 |
Description
The ISL81401AEVAL1Z evaluation board (shown in Figure 4 on page 8) features the ISL81401A, 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 optimizethe inductor size while the strong gate driver delivers up to 20A for the buck-boost output.
Features
- Wide input range: 6V to 40V
- 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
Typical applications
- Type-C power supply and chargers / Redundant power supplies
- Battery backup
- Battery powered industrial applications / Robot and drones / Security surveillance
- Aftermarket automotive
- Medical equipment
