Features and Benefits
- Complete Step-Down Switch Mode Power Supply
- Wide Input Voltage Range: 4V to 36V
- 1.25V to 5V Output Voltage
- EN55022 Class B Compliant
- 200mA Output Current
- Current Mode Control
- –55°C to 125°C Operating Temperature (LTM8020MPV)
- Pb-Free (e4) RoHS Compliant Package with Gold Pad Finish
- Tiny, Low Profile (6.25mm × 6.25mm × 2.32mm) Surface Mount LGA Package
The LTM8020 is a complete 200mA, DC/DC step-down power supply. Included in the package are the switching controller, power switches, inductor, and all support components. Operating over an input voltage range of 4V to 36V, the LTM8020 supports an output voltage range of 1.25V to 5V, set by a single resistor. Only bulk capacitors are needed to finish the design. The LTM8020 meets the radiated emissions requirements of EN55022. Conducted emission requirements can be met by adding standard filter components.
The low profile (2.32mm) tiny package enables utilization of unused space on the bottom of PC boards for high density point of load regulation.
The LTM8020 is packaged in a thermally enhanced, compact (6.25mm × 6.25mm) and low profile (2.32mm) over-molded land grid array (LGA) package suitable for automated assembly by standard surface mount equipment. The LTM8020 is Pb-free and RoHS compliant.
