Dolphin Integration helps reducing BoM cost of IoT circuits thanks to a Panoply of Over Voltage regulators

Grenoble, France , Dec. 14, 2015 –  For SoCs supplied by Lithium-Ion or Alkaline batteries, the actual voltage ranges from 4.4 V in their life, down to 2.0 V over time. They empower IoT devices, which are most of the time put in sleep mode in order to extend their battery life, requiring ultra low voltage supplies for their Always-on and retention domains.

To comply with these requirements, the use of several stages of regulators is usually needed, increasing BoM cost, PCB area and power consumption: Indeed, an external regulator is dedicated to lowering the battery voltage down to a level of 3.3 V or below, while one or several regulators are dedicated to supplying each power domain.

In order to achieve better optimizations, Dolphin Integration launched its panoply of Over Voltage regulators. The Reusable power kit library now embeds components to regulate voltages down to 0.55 V directly from the battery, leading to BoM cost reduction.

The Over-Voltage (OV) panoply includes regulators at TSMC 55 nm, compliant with the Delta Standard, with diverse optimizations:

• eSR-Niagara is a Switching Regulator suitable for efficiency requirements
• qLR-Aubrey is a Linear Regulator with ultra-low quiescent current
• The Retention Alternating Regulator combines two such regulators with rigorous Control Unit a to optimize both active and sleep modes of a SoC
• An Over Protection module is featured to enable over-voltage operation (up to 4.4 V) while using a standard 3.3 V process

Mindful of the overall SoC optimization, Dolphin Integration offers a complete set of solutions, suitable to reduce BoM cost and Silicon area such as High Density Memories and Standard Cell Libraries compatible for their steady and in-rush current needs.
