SY21036
SY21036 is 1A Synchronous Step-Down Regulator manufactured by Silergy.
High-Efficiency, 40V Input, 1A Synchronous Step-Down Regulator
General Description
The SY21036 high-efficiency synchronous stepdown DC/DC converter operates using a clockcontrol and peak-current-mode control architecture and can deliver 1A load current over a wide input voltage range from 4.5V to 40V. It integrates a main switch and a synchronous switch with low RDS(ON) to minimize the conduction loss and Features very low quiescent current to achieve high efficiency under light load.
The 2MHz switching frequency permits low output-voltage ripple and reduces external inductor and capacitor sizes. The SY21036 also provides thermal shutdown, hiccup short-circuit protection, and internal soft-start to limit inrush current during power-on.
The SY21036 is available in a pact SOT23-6 package.
