Beschreibung
The LMR71915EVM-FLBK is a Fly-Buck™ converter that uses the LMR71915FDDAR to produce a regulated 12V output capable of supplying a 625mA load on the primary side of the transformer with a switching frequency of 500kHz. A reflected output of 12V, providing up to 625mA, is available on the secondary side of the transformer. The LMR71915FDDAR is a synchronous buck converter with a wide input voltage range, integrated power MOSFETs, overcurrent protection and precision enable. The device is rated to operate over a junction temperature range of –40°C to +150°C.
Eigenschaften
- Wide input voltage range from 36V to 115V
- Fixed 3ms soft start
- COT mode control architecture
- Peak and valley current-limit protection
- FPWM mode for Fly-Buck converter capability
- SOIC-8 package for ease of use
Typische Anwendungen
- Battery pack - e-bike, e-scooter, LEV
