The PD5C335 is a nonisolated, low-frequency switching regulator module. It integrates a PWM controller, MOSFET, and inductor in a single package. This module typically delivers an output power up to 4.5 W and has a switching frequency range between 1 kHz to 800 kHz, depending on the chosen product type. Its 18 V to 60 V input voltage range covers the majority of general-purpose unregulated input sources available on the market today. Thanks to a wide range of fixed output voltages, the device can be applied in a variety of applications. It is ideal for powering DC and low-frequency AC loads such as fans and motors.

The PD5C335 is a very versatile, multifunctional device. It can provide different kinds of outputs, such as current-mode buck (step-down) or boost (step-up) converters, low-dropout linear voltage regulators, as well as voltage regulators and current limiters suitable for use in automotive, telecom and commercial equipment. It is also able to deliver current-mode buck-boost and buck converters with high efficiency, which makes it suitable for battery-powered applications.

The PD5C335 has an internal comparator for switching frequency modulation. The PWM controller can be turned on or off through its EN/GATE pin, allowing the designer to implement various current-mode or voltage-mode control schemes. It also offers a wide range of operation modes, including continuous, burst, skip, and pulse-modulated or average-modulated mode. Due to its constant on-time, the PD5C335 can be used in DC motors and other low-frequency AC applications to achieve superior efficiency.

The PD5C335 module features a wide range of protection features, including overcurrent protection, short circuit protection, undervoltage lockout (UVLO), and overtemperature protection. The module also has a built-in soft-start feature that enables the controller to be turned on and off without an external capacitor. The device also has an adjustable soft-stop feature, which reduces the output voltage and current when it is abruptly turned off.

The PD5C335 is a highly advanced, low-frequency switching regulator that is ideal for powering dc and low-frequency ac loads such as fans and motors. Its versatile design allows it to be used in a wide variety of applications and makes it suitable for use in battery-powered applications. Thanks to its wide range of protection features, it is suitable for use in commercial, automotive, and telecom equipment. The adjustable soft start-stop feature ensures that the output voltage and current are reduced when the device is abruptly turned off, protecting the system from damage.
