DFR0571

DFR0571 is a DC-DC buck-mode power module. This is a DC-DC buck-mode power module, with input voltage range 8V~28V and fixed output voltage/current 5V/1.6A. Its work frequency can reach to 0.5MHz. The module has high conversion rate and is small in size, easy to embed. Besides, it has steady output voltage, which can work long time without voltage shift and is suitable for the occasions with high requirements. This product can work with some high-capacity and high-voltage batteries to DIY some mobile power. It can also be embedded into your project to provide multiple power options. Suitable for power supply for controller main-board, DIY current source, floodlight, DIY toy car, communication device, digital radio applications.

• Small size, stable performance, wide voltage range for a variety of DIY applications
• Output accuracy is ±0.1V
• Maximum output peak current is 3A
• Full-load output ripple is Vpp less than 50mV
• No-load current is IQ 0.5mA
• Service life of 50000h
• Installation method: chip-mounting or 2.54mm pin plug-in
• Switch-Off function not support and without isolation features
• Operating temperature range from -20 to +85°C
• Dimension is 16.5×22mm/0.65×0.87inch

Notes

The input voltage must within 28V. Load current should not be in 3A or above for a long time, otherwise it will affect the service life of the module and even burn out. If the load current is relatively high, you should increase the minimum input voltage to ensure normal operation.
