SY21036 - 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.

Key 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 compact SOT23-6 package. Features.
  • 4.5 to 40V Input Voltage Range.
  • 1A Output Current Capability.
  • Low RDS(ON) for Internal Swit.

SY21036 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.
