Ricoh Electronic Devices - Smart Energy
Product line include - Power Management ICs, Real-time clock ICs, PC Interface and Communication LSI / Image Processing LSI.
Power Management ICs - DC/DC Converters, Battery Management, Watchdog Timer(W.D.T.) and Voltage Regulators.
The R1218x Series are PWM control type step-up DC/DC converter ICs with low supply current. It is fully dedicated to drive White LED with constant current.
Constant current can be set with an external resistance value. Dimming control is possible by PWM signal for CE pin. Feedback voltage is 0.2V, therefore power loss by current setting resistor is small and efficiency is good.

Fairchild Semiconductor - Power Optimization
The lighting is moving from power hungry incandescent bulbs to fluorescent, LED or HID lamps. Fairchild Semiconductors have designs for Lighting applications too.
This motion Smart Power Module SPM evaluation board is designed to evaluate Fairchild Semiconductor’s SPM3V2_V4 and SPM45H SPM families of parts.
The motion SPM is installed as the motor power module on the evaluation board to drive a three-phase AC Induction Motor (ACIM), Brushless DC (BLDC) motor, Brushless AC (BLAC) motor, or Permanent-Magnet Synchronous Motor (PMSM). A Switched-Mode Power Supply (SMPS) is integrated into the design, along with the necessary bulk capacitors and microcontroller (MCU) interface circuitry.

NO - Normally Open - when the relay is not energized or activated, this terminal is open-circuit.
NC - Normally Closed - when the relay is not energized or activated, this terminal is closed circuit.
COM - The Common Center Terminal in relays. This is the center terminal that closes circuit with NC-NO.
The terminals are potential free and floating and are insulated from the control signals or coil windings by many kilo volts. Many provide visible isolation. These terms apply to SSR or Big Contacters too.
Solid State Relays - SSR
They are called SSR as there are made of semiconductors and have no moving parts to wear out. They do generate heat depending on load and switching. Thyristors are used in most as they are rugged, mosfets and IGBT may also be used for various applications.
In this section you will find SSR designs and PCB layouts which you can study. These were made and sold by me years ago. So the PCB layouts have gone thru some revisions and they worked quite well.
Many machines and equipment use some SSRs in their products which may need replacement. So the SSR is not only sold to OEMs but also to Service-Maintenance Market. These are also modified as Output Modules for digital outputs coming from embedded systems or Computers.

Allegro MicroSystems - Power ICs and Hall-effect sensors
Sanken Products include Regulator ICs, Switching Regulators, Off-Line Flyback Regulators, Stepper Motor Unipolar Drivers, Inverter Power Modules.
50 to 200 A Integrated Conductor Sensor ICs
"The device consists of a precision, low-offset linear Hall sensor circuit with a copper conduction path located near the die. Applied current flowing through this copper conduction path generates a magnetic field which is sensed by the integrated Hall IC and converted into a proportional voltage. Device accuracy is optimized through the close proximity of the magnetic signal to the Hall transducer."
