The BD8966FVM-TR is a high-efficiency, low-cost pulse width modulation (PWM) controller designed for DC-DC switching regulators. The BD8966FVM-TR has an adjustable fixed frequency oscillator and uses a current mode control architecture to provide optimum performance with low output voltage ripple. This PWM controller is ideal for applications such as battery-powered equipment, notebook PCs, and other high-efficiency DC-DC applications.

The output voltage of the BD8966FVM-TR can be adjusted through an external divider network. An internal over-voltage protection circuit provides a power-on reset, keeping the output voltage in the safe range. A soft-start circuit allows a gradual startup, preventing overloading and dropping of the input voltage. A temperature compensated band gap reference is also included to ensure temperature stability under high temperature cycling.

The BD8966FVM-TR has internal control logic for fast switching currents to reduce switching losses. The device has speed mode compensation ability and a Non-Sync Frequency fold-back feature to improve transient response and reduce power dissipation. The high-side and low-side drivers feature high-responsivity and fast turn-on times.

The BD8966FVM-TR can handle up to 8A output current. The device operates with 5V to 40V input voltage range and the output voltage is adjustable from 1.3V to 24V. The onboard 100 kHz fixed frequency oscillator is adjustable through the FB pin, and it can be disabled. Internal digipot allows fine adjustment of switching frequency to maintain optimum efficiency while reducing output noise when the load current increases.

The BD8966FVM-TR is suitable for a variety of applications such as CPU/GPU Core Voltage Regulation, Battery Charging, Netbook/Notebook PCs, and Server Power Supplies. It has built-in protection features such as thermal shutdown, short-circuit protection, and over-current protection, making it a reliable and versatile solution.

The BD8966FVM-TR is based on the same current-mode switching regulator architecture used in industry-standard PWM controllers. It uses a voltage feedback to detect the output voltage and correct the width of the pulses accordingly. It also utilizes current sensing to detect the output current and reduce the width of the pulses when an overload is detected. These features provide stable performance and reliable operation.

The BD8966FVM-TR is a versatile and cost-effective solution for DC-DC converters and battery charging systems. Its internal protection features make it suitable for a wide range of applications, and its high efficiency and high-speed switching make it an ideal choice for high-power applications. The device is also RoHS compliant, making it an environmentally friendly choice.
