ISL6441EVAL is an evaluation kit for INTERSIL ISL6441, ISL6443 products, including evaluation board and documentation. ISL6441, ISL6443 are high-performance, triple-output controllers.
The ISL6441EVAL is a fully assembled, tested evaluation board for the InterSil ISL6441 and ISL6443 power‑management ICs. It includes the board itself, a data‑disc and reference documentation. The board features a 4‑layer PCB with jumpers, test points and connectors for easy evaluation of the three‑output controller.
The manual provides an overview of the board layout, power‑supply connections, voltage‑adjustment methods, soft‑start and shutdown functions, synchronization of multiple boards, and protection features. Detailed component lists and recommended test equipment are also included. This manual is written in Chinese.
| Input voltage range | 4.5 V – 24 V |
|---|---|
| VOUT1 output voltage | 3.3 V |
| VOUT2 output voltage | 5 V |
| VOUT3 output voltage | 2.5 V |
| PWM controller frequency | 1.4 MHz |
A regulated power supply of 45 V‑30 V and 5 A is recommended.
Place a shorting piece on jumper JP2 to cancel the PWM1 (VOUT1) output.
Remove resistor R17 and solder a 1 kΩ resistor on R19; the SYNC pulse can then be observed with an oscilloscope.
