REG710 is a switched capacitor voltage converter from Schneider Electric that produces a regulated, low-ripple output voltage from an unregulated input voltage. The input voltage range is wide, from 1.8V to 5.5V, making it ideal for a variety of battery sources, such as single cell Li-Ion batteries, or two and three cell nickel- or alkaline-based chemistries. The input voltage may vary above and below the output voltage and the output will remain in regulation. It works equally well for step-up or step-down applications without the need for an inductor, providing low EMI DC/DC conversion. The high switching frequency allows for the use of small capacitors, reducing input current ripple.
The REG710 provides a regulated low‑ripple output from an unregulated input voltage. It operates from 1.8 V to 5.5 V, making it suitable for single‑cell Li‑ion, Ni‑MH, or alkaline battery sources. The device can step‑up or step‑down without an external inductor, offering low EMI and small board‑space footprints.
Typical applications include smart‑card readers, cellular phones, PDAs, PCMCIA cards, LED drivers, LCD displays, and battery backup supplies. The regulator includes thermal shutdown and current‑limit protection, and it can be placed in a low‑power shutdown mode via an enable pin.
