R1244N001B
1.2A, 30V Step Down DC/DC converter
NO.EA-293-111123
OUTLINE
The R1244N001B is CMOS-based Step-down DC/DC converter with an internal N-channel high side Tr. (RDSON Typ. 0.35Ω) power switch. The R1244N001B can provide the maximum 1.2A output current. The IC consists of an oscillator, a PWM control circuit, a reference voltage unit, an error amplifier, phase compensation circuits, a slope compensation circuit, a soft-start circuit, protection circuits, an internal voltage regulator, and a switch for a bootstrap circuit. To make a step-down DC/DC converter with the R1244N001B, as external components, an inductor, resistors, a diode, and capacitors are necessary.
