SY21034 High-Efficiency, 200kHz, 100V Input, 0.6A Asynchronous Step-Down Regulator General Description The SY21034 high-efficiency asynchronous stepdown DC/DC regulator can deliver 0.6A current over a wide input voltage range from 4.5V to 100V. It uses constant-off-time and peak-current-mode control to achieve fast transient response, and integrates a main switch with low RDS(ON) to minimize conduction loss. The 200kHz switching frequency permits low output-voltage ripple and reduces external inductor and capacitor sizes. The SY21034 also provides cycle-by-cycle current limiting and hiccup shortcircuit protection. The SY21034 is available in a compact TSOT23-6 package. Features ● 4.5V to 100V Input Voltage Range ● Up to 0.
