SY21102
Description
The SY21102 high efficiency asynchronous Buck converter can deliver 2A output current over a wide input voltage range from 5V to 40V. The SY21102 employs a constant off-time and peak current mode control strategy to achieve fast transient responses. It integrates a power MOSFET with low RDS(ON) to minimize conduction loss.
The 800k Hz switching frequency permits low output voltage ripple and reduces external inductor and capacitor sizes. The SY21102 also provides cycle-by-cycle current limit protection, over temperature protection, and output short circuit protection.
The SY21102 is available in a pact SOT23-6 package.
