产品概述 返回TOPefP嘉泰姆
CXSU63144系列是一组PWM控制的升压DC/DC转换器。CXSU63144系列采用CMOS工艺和激光微调技术从而达到了低功耗和高精度。 芯片自带的相位补偿和缓启动电路使得它有很好的瞬态响应和性能。输出电压可以在2.0V到7.0V范围内以0.1V间隔选择(±2.5%)。振荡频率也可以在三个频率50,100,和180kHz (±15%)中选择。每一种内置开关管型仅使用三种外部器件就可以组成一个升压电路：电感,二极管和电容。5脚封装可以提供降低功耗的CE功能。The CXSU63144/CXSU63145 series is a group of PWM controlled and PWM/PFM controlled step-up DC/DC converters. The built-in
1.4Ω switching transistor type enables a step-up circuit to be configured using only three components, a coil, a diode, and a
capacitor.
Output voltage can be selectable in the range from 2.0V to 7.0V in increments of 0.01V (accuracy:±2.5%). Oscillation
frequency is also selectable from 50kHz, 100kHz, and 180kHz (accuracy:±15%) for the CXSU63144 and the CXSU63145 series.
Soft-start time is internally set and offers protection against in-rush currents when the power is switched on and prevents
voltage overshoot. Packages with CE (chip enable) pin are also available which can reduce the IC power consumption
during during stand-by mode.
The CXSU63144 series is the standard PWM controlled products. The control of the CXSU63145 series switches from PWM to PFM
control during light loads when automatically switching is selected and the series is highly efficient from light loads to large
output currents.efP嘉泰姆
