Overview
R1204x Series
Step-up DC/DC Converter with Shutdown Function
No.
EA-284-180511
OUTLINE
The R1204x is a low supply current PWM step-up DC/DC converter.
Internally, a single IC 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), a soft-start circuit, a maximum duty cycle limit circuit, and a thermal shutdown protection circuit.
By simply using an inductor, a resistor, capacitors and a diode as external components, a high-efficiency step-up DC/DC converter can be easily configured.
As protection functions, the IC contains a thermal sh...
