RP400 系列
电流模式PWM/VFM升压DC/DC转换器

  • 概述

    The RP400 Series are CMOS-based automatic switch PWM- or VFM-controlled step-up DC/DC converters. RP400 includes a soft start circuit. By simply using an inductor, a capacitor, a diode, and (resistors) as external components, a high-efficiency step-up DC/DC converter can be easily configured. Due to current mode PWM control, the RP400 provides a fast response and high efficiency. Ceramic output capacitors can be used.

    The output voltage can be selected from the internally fixed or the externally adjustment. The RP400 has an anti-ringing switch that prevents inductor current from ringing in PWM discontinuous mode. RP400 switches automatically to VFM control in low output current, keeping high efficiency. In addition to SOT-23-5 package, a 1.8mm × 2.0mm square DFN(PLP)1820-6 package is also available.
