■OUTLINE
The R1230D Series are PWM step-down DC/DC Converters with synchronous rectifier, low supply current by CMOS process. Each of these ICs consists of an oscillator, a PWM control circuit, a reference voltage unit, an error amplifier, a soft-start circuit, protection circuits, a protection against miss operation under low voltage (UVLO), PWM/VFM alternative circuit, a chip enable circuit, and a driver transistor.
■FEATURES
●Built-in Driver ON Resistance • • • • • • • • • • • • •P-channel 0.35Ω, N-channel 0.45Ω(at VIN=3V)
●Built-in Soft-start Function (TYP. 1.5ms), and Latch-type Protection Function (Delay Time; TYP. 1.5ms)
●Two choices of Oscillator Frequency • • • • • •500kHz, 800kHz
●PWM/VFM alternative with MODE pin • • • • • •PWM operation; MODE pin at “L”,
VFM operation; MODE pin at “H”
●High Efficiency • • • • • • • • • • • • • • • • • •TYP. 90
●Output Voltage • • • • • • • • •Stepwise Setting with a step of 0.1V in the range of 1.2V ∼4.0V(XX1A/B Type)
or adjustable in the range of 0.8V to VIN(001C/D Type)
●High Accuracy Output Voltage • • • • • • • • • •±2.0(XX1A/B Type)
●Package • • • • •SON8 (Max height 0.9mm, thin type)
■APPLICATIONS
●Power source for portable equipment.
