Description
The R1230D Series is a PWM step-down DC/DC Converter with synchronous rectifier. It features low supply current by CMOS process. Each IC in this series 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.
Specifications and 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)
Application Scenarios
The R1230D Series is suitable for use as a power source for portable equipment.
