ICL828IH-T中文資料INTERSIL數(shù)據(jù)手冊(cè)PDF規(guī)格書(shū)

The ICL828 IC performs supply voltage conversions from positive to negative for an input range of +1.5V to +5.5V resulting in complementary output voltages of -1.5V to -5.5V. The ICL828 has a 12kHz internal oscillator and requires two capacitors to invert the supply voltage. Cascading may be made to increase the output voltage. The high efficiency (greater than 90 over most of the load-current range) and low operating current (60μA typical) make these devices ideal for both battery-powered and board-level voltage conversion applications.
