ABLIC Inc. launched the S-85M0A Series of ultra-high efficiency step-down switching regulators for wearable and IoT devices.
The IC in the step-down switching regulator repeatedly turns a switch on and off. The resulting charges generated in the coil are stored in a capacitor and used to convert the battery voltage. It converts the 3.6 V battery voltage (from a lithium-ion battery) to the proper voltage (1.8 V or 2.5 V) for mobile devices such as a smart phone.

| Typical Application Circuit. |
The S-85M0A Series of ultra-high efficiency step-down switching regulators is housed in the WLP-6L, the industry’s most compact package (1.25 × 0.79 × t0.55 mm), and achieves an ultra-low current consumption of 260 nA, the industry’s top-class current consumption. It reduces the footprint of the mounting area and the surrounding components by 52% compared to our previous product.
