Introduction

The BLL2310C is a high-efficiency, fully integrated, DC-to-DC step-down switching regulators, capable of delivering up to 2A of output current. This device offers two operation modes, PWM and PFM switching control modes, which allows a high efficiency over the wider range of the load.
The BLL2310C guarantees robustness with hiccup-mode output short-circuit protection, cycle-by-cycle current limit, input voltage protection, under voltage lockout and thermal shutdown.
The BLL2310C requires a minimum number of readily available standard external components and is available in a 6-pin SOT23 ROHS compliant package.
