SP3313
36V, 100% Duty Cycle CC&CV Buck Convertor
DESCRIPTION
SP3313 has an optimum input voltage, step-down converter that operates in either CV (Constant Output
Voltage) mode or CC (Constant Output Current) mode. The maximum input voltage is up to 36V and the
operation input voltage from 7.5V to 32V.
MOSFET, what build in 35mΩ High-Side and 25mΩ Low-Side, could deliver up to 3.5A of continuous
output current and the output current accurate to within ±7%.
No external compensation component requirement. The line compensation and the constant current
can be set by an external resistance.
Independent output voltage protection suits for BC1.2 and QC2.0/3.0 dual channel output voltage.
In conclusion, SP3313 is a full function and high performance, high reliability buck DC-DC converter.
