R1202x Series STEP-UP DC/DC CONVERTER with SHUTDOWN FUNCTION NO.EA-255-230823 OUTLINE The R1202x Series are CMOS-based PWM step-up DC/DC converter ICs with low supply current. Each of these ICs consists of an NMOS FET, NPN transistor, 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), a soft-start circuit, a Maxduty limit circuit, and a thermal shutdown protection circuit. By simply using an inductor, a resistor, and capacitors as external components, a high-efficiency step-up DC/DC converter can be easily configured. At the standby mode, a rectifier transistor can separate the output from the input.
