Typical Application


The SY21212A is a high efficiency, current-mode control Boost regulator. The device integrates a 130mΩ low RDS(ON) N-channel MOSFET for high efficiency. The fixed 1MHz switching frequency and internal compensation reduce external components size and count. The build-in internal soft start circuitry minimizes the inrush current at start-up.

The SY21212A is available in compact SOT23-6 package.
