R1240x Series 1.2 A, 30 V Step-Down DC/DC Converter NO.EA-190-230522 OUTLINE The R1240x is a CMOS-based Step-down DC/DC converter with internal Nch high side Tr. (0.35 Ω), which can provide the maximum 1.2 A output current. The ICs consists of an Oscillator, a PWM control circuit, a Reference Voltage unit, an Error amplifier, phase compensation circuits, a slope circuit, a soft-start circuit, protection circuits, internal voltage regulators, and a switch for boot strap circuit. The ICs can make up a StepDown DC/DC Converter with the following external components: an inductor, resistors, a diode, and capacitors.
