Description
The LM25137-Q1-EVM5D3 evaluation module (EVM) is designed to showcase the LM(2)5137-Q1 dual synchronous buck controller, which is intended for functional safety applications up to ASIL D or SIL 3. The EVM operates over a wide input voltage range of 6.5V to 36V to deliver 5V and 3.3V regulated outputs with better than 1% setpoint accuracy at load currents up to 20A per output.
Features
Dual-channel synchronous buck controller targeted for functional safety applications up to ASIL D or SIL 36.5V to 36V input voltage range, 5V and 3.3V regulated dual outputsLoad currents up to 20A (monitored by IMON1 and IMON2 analog outputs)440kHz free-running switching frequency synchronizable up or down 20% with an external clock signalAutomotive-grade power-stage components, including MOSFETs, inductors and capacitorsFully assembled, tested and proven printed circuit board layout with small footprint
Typical applications
- Infotainment systems and instrument clusters
- Dual outputs for ADAS and body electronics
- Automotive HEV/EV powertrain systems
- High-current automotive electronic systems using 2-, 3- and 4-phase implementations
