1. SKY87000-13-001 Product Overview

The SKY87000-13-001 is a high-efficiency buck regulator developed by Skyworks Solutions, specifically designed for multi-band/multi-mode RF power amplifiers (RF PA), suitable for applications such as smartphones, mobile communication devices, and wireless data cards. The chip integrates an automatic bypass LDO (85mΩ low impedance) to optimise efficiency under different load conditions, providing an adjustable output voltage of 0.4V to 4.25V and supporting an output current of 2A, suitable for wireless communication standards such as WCDMA and GSM/EDGE.

2. SKY87000-13-001 Core Features

Wide input voltage range: 2.7V to 5.5V, suitable for lithium-ion battery-powered systems.

Dynamic output voltage regulation: 0.4V to 4.25V, optimising PA efficiency.

Automatic bypass LDO: 85mΩ low impedance, enhancing transient response (<10μs).

2MHz switching frequency: reducing the need for external inductors (2.2μH) and capacitors (4.7μF).

Small package: 9-WLCSP (1.42 × 1.49 mm), suitable for compact designs.

Low quiescent current: Optimises light-load efficiency and extends battery life.
