Fully Digital-controlled Power Supply Control IC with Interleaved Totem-pole Bridgeless PFC Circuit [MD6753]

Aug. 29, 2024

Product Category: Microcontrollers (MCUs) > Digital Power Management ICs

The MD6753 is a power supply IC that combines an interleaved totem-pole control topology and a bridgeless PFC circuit to allow complex control systems to be fully digital.
With the interleaving control in critical conduction mode, the IC can achieve high-efficient yet low-noise power systems.

To support higher power applications, the MD6753 has a PFC circuit that combines a totem-pole PFC where two power MOSFETs are connected in series and the interleaved operation that uses two of the same circuits in parallel.
The MD6753 employs an interleaved control that shifts the phase of two PFC circuits by 180 degrees to make them operate the same.In this control, the input current I_IN is the sum of the currents flowing through the two inductors, L1 and L2, suppressing the input/output current ripple.This simplifies the input filter and reduces the heat generation of the output electrolytic capacitor, resulting in a smaller capacitor.
Synchronously rectifying the input voltage with Q5 and Q6 removes the diodes from the power line and improves circuit efficiency.


The MD6753 achieves these complex controls with a microcontroller chip and a high-voltage analog chip built into an SOP28 package.
These digitally controlled strategies allow application-specific optimal settings.

Applications

For devices requiring high power supplies such as:
• Audiovisual Equipment
• Office Automation Equipment (e.g., Server, Multifunction Printer)
• Industrial Equipment
• Communication Equipment

Sinusoidal, High-voltage, 3-phase Motor Drivers to Bring Ideal Inverter Control Solutions for Low- to Middle-capacity Motors [SX68127MA, SX68128MA]

May 27, 2024

Product Category: Power Modules, IPMs > Intelligent Power Modules (IPMs)

The SX6812xM series are high voltage 3-phase motor drivers that support Hall element and Hall IC inputs.
In addition to the existing SX68128MB that supports 10-pole DC motors, we have added new drivers to this series: the SX68127MA (1.5 A) and the SX68128MA (2.0 A), which support 8-pole DC motors.

These drivers employ a sinusoidal motor driving control that is excellent in efficiency and quietness.
The SX6812xM series comes in a thin SOP36 package, where a controller, a gate driver, output transistors for each phase, and bootstrap diodes are highly integrated. This helps you create a motor drive circuit using only an SX6812xM series device and Hall elements.
Along with typical protections, this series has extensive functions: the motor lock protection, the reverse rotation detection, and the Hall signal abnormality detection. This enhanced functionality allows your application to have significantly fewer components, a smaller PCB area, and higher reliability.

The SX6812xM series will be best suited to inverter control systems using low- to medium-capacity motors compliant with universal input standards, such as fan motors for air conditioners, air purifiers, and electric fans.
