USB 5V 2.5A Output, 42V Input Synchronous Buck with Cable Drop Compensation Download White Paper 472Ko

The LT®8697 is a compact, high efficiency, high speed synchronous monolithic step-down switching regulator designed to power 5V USB applications. A precise output voltage and programmable cable drop compensation maintain accurate 5V regulation at the USB socket connected to the end of a long cable. Forced continuous operation allows the LT8697 to sink current, further enhancing accurate 5V regulation during load transient

This month, Trinamic Motion Control is offering you to win one of four TMCM-1043 development kits for its highly integrated, NEMA 17-compatible TMCM-1043 stepDancer stepper motor module.

Offering designers an easy-to-use PC-based GUI that allows one-click modification of motor drive current, micro-stepping and other key parameters, the intuitive kits are custom designed and developed for direct mounting on a NEMA 17 motor. Pre-programmed and pre-configured with all operating parameters to support standard 1.5A (peak) motors, the TMCM-1043 board uses Trinamic´s single-axis TMC2660 stepper motor driver IC, which integrates a motor pre-driver and power MOSFETs.
