The PD IM-7648T4H is part of the Evaluation Boards - DC/DC & AC/DC (Off-Line) SMPS family. It’s a pulse width modulation (PWM) controller, and is primarily used for low power offline SMPS applications. It’s also suitable for standby mode flyback and forward converters. With its integrated one-cycle primary current control, the IM-7648T4H is one of the few controllers available capable of controlling zero-voltage switching (ZVS) over the full microcontroller power range. As an integrated solution, the IM-7648T4H has pre-programmed settings that ease design and start-up complexity, which then allows for speedy time-to-market and cost savings.

The IM-7648T4H works by maintaining a constant DC output voltage despite varying line and load conditions. When the load is drawing a current, the primary output current is increased. When the load is not drawing a current, the output current is decreased. This constant DC voltage is achieved through a series of pulse width modulation (PWM) adjustments that are made as the line and load conditions vary. The IM-7648T4H also has an adjustable frequency and PWM control to ensure that the output voltage is always within the tolerance range.

One key feature of the IM-7648T4H is the ability to provide fast transient response times due to the integrated one-cycle primary current control. This allows for a quick response to changes in load or line conditions, thus allowing for improved system reliability and sustained high efficiency. Additionally, the IM-7648T4H has a self-protection circuit that detects short-circuit faults. This circuit then shuts down the output and triggers a fault latch on the primary board. The fault can then be reset by returning the power switch to its original position.

The PD IM-7648T4H controller is capable of handling a wide range of input voltage. It has two selectable input voltage operating modes—DC and AC. The design supports up to 300V DC and 265V AC input. The IM-7648T4H also has a wide range of output voltage options with a maximum output of 400V. The minimum output voltage supported is 0.4V, allowing for very low output voltages. It also supports a wide range of output power, from 5 to 50W, which is suitable for many types of low power applications.

The IM-7648T4H also has a built-in soft start feature. This feature allows for a gradual, fast start-up to prevent issues with both the line and the load. Additionally, it also offers programmable coverage for various safety standards. This includes protection against short circuit, overvoltage, overcurrent, over temperature, and surge protection.

The IM-7648T4H can also be used for buck, boost, flyback, and forward converters. The IM-7648T4H can also provide enhanced power efficiency in these applications due to its one-cycle primary current control. The controller also offers a peak current mode control for better load line and stress management, resulting in improved power efficiency and better component utilization.

Overall, the PD IM-7648T4H controller is an ideal solution for low-power offline SMPS applications due to its wide range of input voltage, output voltage, and output power ranges. The integrated one-cycle primary current control allows for fast transient response times for improved system reliability and sustained high efficiency. The flexible range of safety standards also ensures that the circuit is protected from a variety of deficiencies. Additionally, the built-in soft start feature adds further reliability to the design.
