R1245x Series
AEC-Q100 Grade 2 Certified
1.
2 A, 30 V Step Down DC/DC Converter for Automotive Applications
NO.
EC-269-140311
OUTLINE
The R1245x is a Step-down DC/DC converter with internal N-channel high side Tr.
That is developed with CMOS process technology.
The ON resistance of the built-in high-side
transistor is 0.
35 Ω and the R1245x can provide the maximum 1.
2 A output current.
Each of the ICs consists of an oscillator, a PWM control circuit, a voltage reference unit, an error amplifier, a phase compensation circuit, a slope compensation circuit, a soft-start circuit, protection circuits, an internal voltage
regulator, and a switch for bootstrap circuit.
The ICs can make up a step-dow...
