Pin Number 1 2 3 4 5 6 7 8 Disable Pad Name VDD RSW-OSC CS LX GND VB VA REL-OSC DIS Function Positive voltage supply for the IMP527. Inductor L may be connected here or to a separate supply. Switch-mode resistor pin. Switching frequency is determined by external resistor RSW, connected between pi.

IMP52 7 POWER MANAGEMENT Single Cell Battery Powered Electroluminescent Lamp Driver/Inverter The IMP527 is an Electroluminescent (EL) lamp driver designed for systems that must operate down to 1 volt and below. The input supply voltage range is 0.9V to 2.5V. Typical output lamp drive voltage is 180V. All four EL lamp-driving functions are on-chip. These are the switchmode power supply, its high-frequency oscillator, the high-voltage H-bridge lamp driver and its low-frequency oscillator. EL lamp.
