IP05 - Advanced Programmer

Product highlights

• Multifunction Programmer
• Dual Channel Output
• SWD/JTAG Programmer
• UART Serial Interface
• 4 A Power Supply Capacity

Overview

This xCHIP is based on the FT2232H, which is a USB 2.0 High Speed interface IC supporting a dual channel architecture with interfaces for UART, SWD and JTAG. IP05 is designed to power, interface with and program almost every xCHIP. The on-board SC185 is a 4 A synchronous step-down regulator to provide power to the system bus. It is optimized for maximum efficiency over a wide range of load currents. During full load operation, the SC185 operates in PWM mode with fixed 1.5 MHz oscillator frequency. As the load decreases, the regulator has the option to transition into Power Save mode maintaining high efficiency or stay in forced PWM mode operation.
