R1218K021A Step-up DC/DC converter

R1218x SERIES Step-up DC/DC converter for White LED Backlight NO.EA-166-170906 OUTLINE The R1218x Series are PWM control type step-up DC/DC converter ICs with low supply current. The R1218x is fully dedicated to drive White LED with constant current. Each of these ICs consists of an NMOS FET, an oscillator, a PWM comparator, a voltage reference unit, an error amplifier, a current limit circuit, an under voltage lockout circuit (UVLO), an over-voltage protection circuit (OVP). The R1218x can d.
