Product Overview

The MAX734CSA+ is a 12V, 120mA flash memory programming supply in 8 pin NSOIC package. The MAX734 is a 12V output step-up DC to DC switch mode regulator. It delivers a 120mA from a 4.75V input and is ideal for programming flash memories. It uses only a diode, an 18µH inductor and two 33µF capacitors. It also features a logic controlled shutdown pin that allows direct microprocessor control. In-circuit testing ensures overload, line and temperature limits. The operating supply current can be reduced to less than 500µA by toggling the shutdown pin with the µP. It uses current mode pulse width modulation control to provide precise output regulation and low subharmonic noise. A fixed 170KHz oscillator frequency facilitates ripple filtering and allows the use of tiny external capacitors.
  • Efficiency is 85%
  • Operating temperature range from 0°C to 70°C
  • Operating quiescent current is 1.2mA
  • Shutdown supply current is 70µA
  • Line regulation is 0.20%
  • V and load regulation is 0.0035%
  • mA
