MAL219699003E3: SuperCap Charger and Backup Power Supply

Summary

MAL219699003E3 mini charger, from Vishay, and backup demonstration circuit is a fully transparent charger unit that uses a BQ24095 charging IC and TPS610997 boost converter IC from Texas Instruments to boost the capacitor voltage up to a 5 V constant output voltage.

This mini charger is equipped with a 90 F / 4.2 V 196 HVC ENYCAPTM hybrid energy storage capacitor, which is charged through the power input. This power input is compatible with a USB port. The charged energy is buffered in the 196 HVC capacitor and can be used for backup power.

An independent fixed output voltage of 5 V is created from the backup power of the hybrid capacitor by the TPS610997 synchronous boost converter IC, which provides a constant output voltage with very high efficiency.
