概述
描述
The ISL854102DEMO2Z demo board uses the ISL854102 synchronous buck regulator in an isolated buck configuration. The board is configured for a 19V to 40V input voltage range. The primary output is 12V, capable of 800mA, and the dual secondary outputs are +12V and -12V, capable of ±150mA each.
特性
- Wide input voltage range of 3.5V to 40V
- Synchronous operation for high efficiency
- Integrated high-side and low-side NMOS devices
- Internal fixed (500kHz) or adjustable (300kHz to 2MHz) switching frequency
- Continuous output current up to 0.8A at primary output and ±150mA at secondary outputs
- Internal or external soft-start
- Minimal external components required
- Power-good and enable functions available
