描述
The ISL854102DEMO2Z demo board uses the ISL854102 synchronous buck regulator in an isolated buck configuration. The board is configured for 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
