EV4541-N-00A

EV4541-N-00A is an evaluation board designed to demonstrate the capabilities of MPS’s MP4541, a high-efficiency, synchronous step-down converter with integrated high-side and low-side MOSFETs. The MP4541 provides 0.8A of output current in a buck topology from up to an 80V input power supply. The MP4541 supports high-efficiency pulse skip mode (PSM) under light-load conditions. Valley current limit circuits protect against overload and short circuit conditions. The MP4541 is available in an SOIC-8EP package. Applications include high voltage battery packs, industrial power supplies and printer power boards.

• 8V to 80V input voltage, 1V to 30V output voltage
• 90% maximum operation duty cycle
• 625mohm/380mohm internal MOSFETs
• Constant-on-time control mode
• Configurable 100KHz to 1MHz frequency
• Internal soft start and loop compensation
• Overcurrent protection (OCP) and short-circuit protection (SCP) with hiccup mode
• High efficiency PSM at light-load
• Output voltage VOUT of 5V
