The EVHR1211-Y-00B is an evaluation board designed for lithium-ion batteries, which are typically used in e-mobility applications and uninterruptible power supply (UPS) applications. This device can also be used as a general power supply unit.
If there is not a battery present, then the EVHR1211-Y-00B regulates the output voltage (VOUT) to 58.8V. This solution is based on the HR1211, a PFC + LLC combination controller from a single integrated circuit.
