Texas Instruments LMR71915FDDAR | Demoboard LMR71915EVM-FLBK
LMR71915EVM-FLBK Fly-Buck™ converter evaluation module
Overview
| Topology | Buck Converter |
| Input voltage | 34-115 V |
| Output 1 | 12.37 V / 0.62 A |
Description
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.
Features
- 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
Typical applications
- Battery pack - e-bike, e-scooter, LEV
- Industrial battery pack (≥ 10S), Factory automation - PLC, Generic isolated bias supplies in industrial, automotive, and telecom systems,
- Communications - brick power module
