R1200x SERIES

STEP-UP DC/DC CONVERTER FOR OLED BACK LIGHT with SHUTDOWN FUNCTION

NO.EA-192-130502

OUTLINE

R1200x series are CMOS-based control type step-up DC/DC converter with low supply current ICs. Each of

these ICs consists of a Nch MOSFET, NPN transistor, an oscillator, 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), and a soft start circuit. As the external components, an inductor, resistances or capacitors are necessary

to make a constant output voltage of step-up DC/DC converter with the R1200x. At standby mode, the NPN

transistor can separate the output from the input. During the situation of that, there are two versions.

R1200xxxxA: the output of V^OUTis generated to 0V by the low resistance (with the auto discharge function).

R1200xxxxB does not generate the output of V^OUT(without the auto discharge function).

The soft-start time (Typ. 1.5ms) and the maximum duty cycle (Typ. 91%) are set internally. For the protection

functions of R1200x series are the current limit function of the LX peak current, the OVP function for detection the

over voltage of output and the UVLO function for protective miss-operation by the low voltage. (The threshold of

OVP is selectable from 17V, 19V or 21V.)

Since the packages for these ICs are DFN1616-6, DFN(PLP)1820-6, SOT-23-6 and WLCSP-6-P1

(Non-promotion), therefore high density mounting of the ICs on boards is possible.
