The small package provides more than 40% space savings compared to a discrete implementation. The TinyBuck device is also more energy efficient, offering up to 95% efficiency compared to alternate solutions. To accommodate the requirements of a broad variety of non-isolated DC-DC designs, the new regulator provides a wide input operating range from 6.5V to 24V.
The new buck regulator features a pre-bias startup to regulate the output cap discharge during soft-start conditions, protecting the system ICs from damage. It provides a suite of protection features incorporating soft start, under voltage lockout (UVLO), thermal shutdown, over voltage and over current protection to protect the system from fault conditions.
The new regulator also has a sync pin enabling synchronization to an external clock, which decreases input ripple in the system and reduces the costs of the input capacitors. This sync pin allows the system to operate over one FAN21SV06 in a master/slave configuration and decreases EMI-related issues.
The new TinyBuck regulators are part of a comprehensive family of integrated buck regulators. This newfamily incorporates the FAN2103, FAN2106, and FAN2108, that provides high efficiency for graphic cards, set-top boxes, servers and point of load (POL) applications. Additionally, the new FAN2106, a 6A version, won the prestigious 2007 EDN China Innovation award. It also won the 2007 Electronic Design and Application World- Nikkei Electronics China (EDAW-NEC) award for the DC-DC converter product.
