Overview
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 VOUT is generated to 0V by the low resistance (with the auto discharge function).
R1200xxxxB does not generate the output of VOUT (without the auto discharge function).
The soft-start time (Typ.
1.
5ms) and the max...
