The STEVAL-LLL014V1 evaluation kit features the SPC582B60E1 32-bit automotive-grade microcontroller for controlling the ALED7709 LED driver via an I2C interface. The main board can be configured and controlled via a Mini-USB connection to a PC running the STSW-LLL014GUI software. The kit also includes an LED board with four strings of 10 LEDs.Â
Power Integrations
The RDK-919Q is a development board for the INN3949CQ, a member of the InnoSwitch3-AQ family of power conversion ICs. Operating from an input-voltage range of 50 V to 1000 V dc, ideal for use in 800 V bus systems, the board provides an isolated power supply for loads of up to 60 W, at an output voltage of 24 V. Conversion efficiency is 82%.Â
The RDK-919Q works in hot conditions: at 85°C, it can provide a continuous 20 W output with an input at 1,000 V dc.Â
The board offers all the benefits of secondary-side control with the simplicity of primary-side regulation: it is insensitive to transformer variation, and provides extremely fast transient response which is independent of load timing. The maximum output ripple voltage is 240 mV.

The EV-L99LDLH32GEN board provides a way to connect the L99LDLH32 multi-channel automotive LED driver to an existing system. To connect a lighting load, it is necessary to design a specific adapter board suited to the chosen OLED panel.
Monolithic Power Systems
The Monolithic Power Systems EVQ5850-J-00A evaluation board demonstrates the capabilities of the MPQ5850, a 36 V smart diode controller with reverse protection.
The MPQ5850 diode controller can drive an external N-channel MOSFET to replace a Schottky diode for reverse input protection. The 20 mV ultra-low dropout minimizes power loss and enables a low minimum input voltage, which makes the MPQ5850 well-suited to cold-crank conditions in automotive applications.Â
The 4 μA shutdown current also makes the MPQ5850 ideal for battery-powered applications. The ultra-fast transient response meets the requirements of the ISO16750 standard.
The EVQ5850-J-00A board is fully assembled and tested.
Monolithic Power Systems
The EVQ6615-QK-00A is an H-bridge dc motor driver evaluation board featuring the MPQ6615-AEC1 IC, which operates from an input voltage of up to 40 V.Â
The H-bridge consists of four N-channel power MOSFETs. An internal charge pump generates the gate driver supply voltages for the high-side MOSFETs, and a trickle charge circuit maintains sufficient gate driver voltages for 100% duty cycle operation.
The current flowing through the two Sx outputs is sensed via the internal current-sensing circuits. Each phase has an Output pin which sources or sinks a current proportional to each phase’s output current. Only the current flowing through the low-side MOSFET is sensed. This current is sensed in both the forward and reverse directions.
Internal safety features include over-current protection, under-voltage lockout protection, and thermal shutdown. The input control signals for the MPQ6615-AEC1 are applied through the connector on the board.
The MPQ6615-AEC1 can be used to drive brushed dc motors, door lock and latch motors, and seat actuators.
