製品概要

概要

The STEVAL-ISA141V2 is a product evaluation board based on the STBB3JCC fixed frequency, high efficiency, buck-boost DC-DC converter. The STBB3JCC is capable of driving a HB WLED from a 1.8 V to 5.5 V input voltage supplied by a one cell Li-Ion battery. Thanks to its high switching frequency (2 MHz) it is possible to reduce the size and cost of the external power components. Low FB voltage (100 mV) reduces power dissipation across the external sensing resistor and maximizes the LED current.

特徴
