DC-To-DC Converter Controller
T he PJ34063 Series is a monlthic control circuit
containing the primary functions required for DC to
DC onverters. These devices consist of an internal
DIP-8 SOP-8
duty cycle oscillator with an active current limit
circuit, drive and a high current output switch. This
series was specifically designed to be incorporated in
step-up, step-down and voltage-inverting applications
with a minimum number of external components. Pin : 1. Switch Collector 2. Switch Emitter
3. Timing Capacitor 4. Gnd
temperature compensated reference,comparator,controlled. 5. Comparator Inverting Input 6. Vcc
7. IPK Sense 8. Driver Collector
