GreenPAK™ with Low Drop Out Regulators

GreenPAK™ with Low Drop Out Regulators

Power system design in the age of mobile devices, and especially wearable devices, is more challenging than it has ever been. The end users of these devices want them to get smaller and lighter, while at the same time having longer battery life. These opposing goals, and the need to cost reduce and size reduce the circuit boards, are just a few of the challenges facing the power system designer. Shown below are more of the challenges facing the designer of a power system for mobile devices.

To overcome these challenges, Dialog has developed the concept of “Flexible Power Islands”. Using FPIs, designers can divide their complex power system into some number of local power regions (or islands), each of which includes the power control, power sequencing and power regulation needed to support loads in the immediate vicinity. This technique results in higher performance and a more efficient solution that can be flexibly tailored to the requirements of each individual system.

In some cases, using an FPI can be very useful to augment the functions included in a Power Management IC (PMIC). In this use case, the FPI can support local point-of-load regulation, sequencing and power monitoring. This can result in simpler layout, as well as improved energy and thermal efficiency.

For smaller and simpler systems (which have up to six power rails), the FPI concept can provide most or all of the power system functions needed. In this case, the FPI can serve as a “µPMIC”, but with the added benefit of greater levels of flexibility and customization, with no requirements for NRE.

With the SLG46580, Dialog has captured many of these necessary power system functions (power monitoring, sequencing, reset and power switching) in a tiny 2.0 x 3.0 mm 20 pin fully encapsulated plastic package. Using Dialog’s easy-to-use GUI based GPAK Designer™ and GPAK development hardware, designers can quickly and easily implement their unique configuration of the device, thereby customizing the functions to match their unique power requirements.

The SLG46580 has four LDOs, each with a maximum output current of 150mAs. Each of the LDOs has a programable output voltage level that can be set to one of thirty two different values from 0.9V to 4.35V, and also have programmable options for slew-rate selection and fault detection.

The FPI concept is broadly applicable across a range of end markets, shown below.
