General Description
The RY81020 is a monolithic IC designed for step-down DC/DC converters, featuring low EMI, the ability to drive
2A continuous current, and excellent load and line regulation. The RY81020 can also operate at 98% duty cycle for
low dropout operation, and internal soft-start allows for low inrush currents, extending battery life in portable
systems. In terms of protection features, it features cycle-by-cycle peak current limiting, short-circuit protection,
thermal shutdown and undervoltage lockout.
The RY81020 is available in ESOP8 packages.
