The TPS40140RHHR is a dual or two-phase synchronous buck controller designed for stackable configurations, allowing up to 16 phases for a single output power supply. It operates with an input voltage range of 4.5V to 15V and can convert a 15V input to a 0.7V output at a programmable switching frequency of up to 1MHz per phase. The device supports both interleaved operation for improved input ripple current and independent output configurations. It features a 0.5% internally trimmed 0.7V reference, a shutdown current of 10OºA, and true remote sensing capabilities. The TPS40140 also includes programmable undervoltage lockout and supports prebiased outputs, making it suitable for applications in graphic cards, internet servers, networking, and telecommunications equipment. The device is housed in a 36-pin VQFN package.
