3.3 - 4.2V to 0 - minus 200V step-down DC/DC converter

Overview

180XFAB_DCDC_04 is a DC/DC step-down voltage converter that generates -200V output voltage from 3.3V to 4.2V. The DC/DC consists of OTA and transistor-capacitive voltage multiplier cells. The block is designed for no load at the output at 41uA current consumption for 3.7V input voltage and -155V output voltage a. Shutdown mode is activated by setting en to “0” and turns off the DC/DC converter. Current consumption decrease with output voltage increasing. It will take 20ms to charge external 1nF capacitor from 0 to -200V.
