eGaN DC-DC demo board comes in tiny 1/16th brick size
EPC announces the availability of the EPC9157, a 300 W DC-DC demo board in the tiny 1/16th brick size, measuring just 33 mm x 22.9 mm x 9mm (1.3 x 0.9 x 0.35 in). The EPC9157 demo board integrates the Renesas ISL81806 80 V dual synchronous buck controller with the latest-generation EPC2218 eGaN FETs from […]
Handling the 48-to-12-V stepdown
A multiphase, interleaved buck converter can reduce bus voltage down to something useful in data center server racks. Brad Xiao, Nazzareno (Reno) Rossetti Maxim Integrated Hyperscale data centers that dissipate hundreds of megawatts demand efficient power delivery beyond the ability of the traditional 12-V power supplies on old server motherboards. A data center on 12 […]
Reference design lets secondary MCU control primary power
In modern offline AC-DC power solutions, programmability and adaptive control offer the flexibility and intelligence needed by smart home devices to better interface with their power systems. In these systems, a secondary side microcontroller (MCU) is typically not capable of starting a system without the use of a separate bias power supply. A new reference […]
80 V buck-boost battery charging controller integrates MPPT and I2C
Analog Devices, Inc. introduced the LT8491 buck-boost battery charging controller that features Maximum Power Point Tracking (MPPT), temperature compensation, and an I2C interface for telemetry and control. The device operates from input voltages above, below, or equal to the regulated battery float voltage. The LT8491 offers three selectable Constant Current Constant Voltage (CC-CV) charging profiles, […]
