Description:
Boost led driver.
The H0 is a step-up DC/DC converter with a constant current to drive white LEDs or similar.
The device can drive up to eight LEDs in series from a Li-Ion cell.
The LED current is set by the external resistor (RSET) and is directly regulated by the feedback (FB) voltage (typ: 200mV) across the ex
