SP4446EB

The SP4446EB is one member of the SP4446 family which is designed as one kind of evaluation board device that has a fixed output voltage programmed to +5V (consult the factory for other voltage options). This device is also a completely assembled and tested surface mount board which provides easy probe access points to all SP4446 Inputs and Outputs so that the user can quickly connect and measure electrical characteristics and waveforms.

Features of the SP4446EB are:(1)Easy Evaluation for the SP4446 2V to 7V input to 25 to 30V Output;(2)SP4446 provides up to 30 mA output current;(3)High Efficiency: up to 80%;(4)SOT23-5 Package & SMT components for small, low profile Power Supply.

This device can be powered from inputs from a +1.2 V to +7.0 V, and the output of it will be enabled if the J1 jumper is in the top or pin 1 to 2 position. Also it uses a Murata 10uH inductor with an Isat value of 450mA and a DCR of 0.39ohms, which easily handles the Ipeak of 350mA of the SP4446 and will deliver high efficiencies.
