概述
描述
The WS040-ACDCWIFIEV1Z is a high-efficiency AC/DC switched‑mode power supply (SMPS) solution optimized for always-connected IoT applications. It delivers ultra-low standby power, measuring as low as 5mW, while providing seamless wireless connectivity through integrated Wi‑Fi® and Bluetooth® Low Energy (LE).
The Renesas iW1816, a digital power controller with an integrated bipolar transistor, powers the WS040-2. The iW1816 offers industry-leading average efficiency and one of the lowest standby power profiles available. With advanced primary-side regulation, it reduces the requirement for external components, simplifying design and lowering bill of materials (BOM) cost.
In addition, the DA16600 module features an intelligent power management architecture that disables inactive subsystems to minimize power consumption. When active, it supports ultra-low-power TX/RX modes for efficient wireless data transmission. Together, the iW1816 and DA16600 provide a robust and energy-efficient platform ideal for IoT devices requiring constant connectivity with minimal power draw.
特性
- Primary‑side regulated AC/DC power supply IC with ultra-low standby current
- Integrated Wi‑Fi and Bluetooth Low Energy for persistent low-power connectivity
- Wi‑Fi module configurable for network access using an Android application
- Wireless module can signal the system, via Android app control, to power system blocks on or off
