The ST777/778/779 are dc-dc converters that step-up from low voltage inputs requiring only three external components, an inductor (typically 22µH) and two capacitors. The device include a Sinchronous Rectifier that eliminates the need for an external catch diode, and allows regulation even when the input is greater than the output. SCHEMATIC DIAGRAM VIN 100µ.

Supply current is 270µA under no load and only 20µA in stand by mode. 22µH RLIM 2 IN DELAY TIMER 1 5 ILIM LX ACTIVE RECTIFIER tOFF SWITCH DRIVER DELAY TIMER OUT 6 VO 100µF tON 1 : N RECTIFIER CONTROL PGND 4 SEL 8 VREF 1.25V 7 SHDN SHUTDOWN CONTROL AGND 3 October 2002 1/11 ST777/778/779 ABSOLUTE MAXIMUM RATINGS Symbol VCC LX OUT, SHDN AGND to PGND FB PTOT TSTG TOP Parameter DC Input Voltage to GND Switch .
