STEVAL-6986YT2DL [STMicroelectronics]

The STEVAL-6986YT2DL is an evaluation board based on A6986I.

The STEVAL-6986YT2DL implements an isobuck-boost topology. The input voltage can go up to 24 V.

Thanks to the embedded two secondary windings transformer, a dual isolated output is available (around 20 V and around -5 V).

The isolated output power can reach 5 W.

The peculiarity of this board is its compatibility with a SIP7 module both in terms of pinout and concerning the size.

Further flexibility is achieved by matching SIP7 modules with different output voltage pinouts (available on pins 4-5-6 or 5-6-7)

The STEVAL-6986YT2DL works at 250 kHz switching frequency and embeds all the standard protections offered by the A6986I (against overvoltage, overcurrent and overtemperature events).

The embedded transformer offers 1.5 kV isolation.
