| Output 1 | -15 V / 0.2 A |
| Output 2 | 15 V / 0.2 A |
| IC revision | 1 |
Description
The MAX17690EVKITC is a fully assembled and tested circuit board that demonstrates the working of an isolated 6W no-opto flyback DC-DC converter. This circuit uses a MAX17690 in a 16-pin TQFN package with an exposed pad. The data sheet must be read in conjunction with this quick start guide for demo circuit. The EV kit output is configured for an isolated ±15V and provides up to 200mA of output current on each output. The MAX17690 switches at a 100kHz switching frequency. The transformer provides the galvanic isolation between input and output, up to 1500VRMS.
