LM3691TL-1.2EV/NOPB
| LM3691TL-1.2 Evaluation Board | Full production
Lead Free (RoHS)
|
| $92.00 each | 1 |
| Description:
The LM3691 step-down DC-DC converter is optimized for powering ultra-low voltage circuits from a single Li-Ion cell or 3 cell NiMH/NiCd batteries. It provides up to 1A load current, over an input voltage range from 2.3V to 5.5V. There are several different fixed voltage output options available.
The LM3691 evaluation board is a working demonstration of a step down DC-DC converter. This application note contains information about the evaluation board. For further information on buck converter topology, device electrical characteristics, and component selection, please refer to the datasheet.
Features:
- VOUT = 0.75V to 1.8V
- ± 1% DC output voltage precision
- 2.3 ≤ VIN ≤ 5.5V
- 4 MHz switching frequency
- 64 µ A (typ.) quiescent current in ECO mode
- 1A maximum load capability
- Automatic ECO/PWM mode switching
- Mode Pin to select ECO/Forced PWM mode
- 1 µ H inductor, 4.7 µ F input capacitor (0603(1608) case size) and 4.7 µ F output capacitor (0603(1608) case size)
- Current overload and thermal shutdown protections
- Only three tiny surface-mount external components required (solution size less than 15 mm2)
Applications:
- Mobile Phones
- Hand-Held Radios
- MP3 players
- Portable Hard Disk Drives
