The MAX734 Evaluation Kit is a 12 V step‑up, switch‑mode converter designed to supply a stable 12 V flash‑memory programming rail from low‑voltage sources as low as 4.75 V. It delivers up to 120 mA output current, achieves about 85 % conversion efficiency, and includes a shutdown pin for ultra‑low quiescent current.
The manual provides ordering information, a component list, wiring diagrams, test procedures, troubleshooting charts, and detailed guidance on noise, ripple, EMI, and input‑voltage considerations for both bench‑top and battery‑powered applications.
| Output voltage range | 11.52 V – 12.48 V |
|---|---|
| Maximum output current | 120 mA |
| Conversion efficiency | 85 % |
| Quiescent supply current | 1.2 mA |
| Fixed oscillator frequency | 170 kHz |
| Maximum input voltage | 7 V |
The output voltage will be between 11.52 V and 12.48 V.
The kit is limited to a maximum input voltage of 7 V.
The converter operates at about 85 % efficiency.
Without a soft‑start capacitor the start‑up time is about 1 ms; adding a wire across C3 increases it to 2.5 ms.
