The BLL2311C is a high-efficiency, fully integrated, DC-to-DC step-down switching regulators, capable of delivering up to 2A of output current. This device operates in Forced PWM mode to maintain low output ripple over the full load range.
The BLL2311C guarantees robustness with hiccup-mode output short-circuit protection, cycle-by-cycle current limit, input voltage protection, under voltage lockout and thermal shutdown.
The BLL2311C requires a minimum number of readily available standard external components and is available in a 6-pin SOT23 ROHS compliant package.
