描述
The ISL81805EVAL1Z dual-phase evaluation board features the ISL81805, an 80V high voltage dual synchronous boost controller that offers external soft-start, independent enable functions, and integrates UV/OV/OC/OT protection. A programmable switching frequency ranging from 100kHz to 1MHz helps to optimize inductor size while the strong gate driver delivers up to 5A for the boost output.
特性
- Wide input range: 9V to 36V
- High light-load efficiency in pulse skipping DEM operation
- Programmable soft-start
- Optional DEM/PWM operation
- 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
