| Output 1 | 48 V / 5 A |
| IC revision | 1.00 |
Description
The ISL81805EVAL1Z dual-phase evaluation board (shown in Figure 4) features the ISL81805, an 80V high voltage dual synchronous boost controller thatoffers external soft-start, independent enablefunctions, and integrates UV/OV/OC/OT protection. A programmable switching frequency ranging from 100kHz to 1MHz helps to optimize inductor size whilethe strong gate driver delivers up to 5A for the boost output.
Features
- Wide input range: 9V to 36V
- High light-load efficiency in pulse skipping DEM operation
- Programmable soft-start
- Optional DEM/PWM operation
- Optional CC/HICCUP OCP protection
- Supports pre-bias output with soft-start
- PGOOD indicator
- OVP, OTP, and UVP protection
- Back biased from external to improve efficiency
- Optional input/output average OCP
Typical applications
- Automotive electronics
- Industrial equipment
- Power systems
- Telecommunications, Servers and data centers
