1.5A Rail-to-Rail Output Synchronous Step-Down Regulator Download White Paper 77Ko

The LTC3600 is a high efficiency, monolithic synchronous buck regulator whose output is programmed with just one external resistor. The accurate internally generated 50μA current source on the ISET pin allows the use of a single external resistor to program an output voltage that ranges from 0V to 0.5V below VIN. The VOUT voltage feeds directly back to the error amplifier in unity gain fashion and equals the ISET voltage. The operating supply voltage range is 4V to 15V, making it suitable for dual lithium-ion battery and 5V or 12V input point-of-load power supply applications.

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.
