Update: 30 September, 2023
This product is a PFM inductive boost converter designed for driving 2, 3 or 4 series connected white LEDs from a Li-Ion cell and up to 8 LEDs from a 5V supply. It operates from an input supply of between 2.5V and 5.5V and provides an adjustable output current of up to 50mA. The ZXLD1937 includes the output switch and peak current sense resistor, and can operate with a maximum output voltage of 28V. Typical quiescent current is 60μA and a shutdown function is provided to reduce this current to less than 500nA in the 'off' state.
