The FDW9926A is a high performance two-phase buck controller for DC/DC applications that integrates two low RDS(ON) high-side MOSFETs and two low RDS(ON) low-side MOSFETs. It offers a wide operating range from 4.5V to 64V, with high efficiency and low cost. In addition to the two phase buck control, the FDW9926A also features a programmable Maximum Power point tracking (MPPT) current level, enabling optimal tracking of solar panel output power.

FDW9926A is an array of N-channel MOSFET (metal oxide semiconductor field-effect transistors) that acts as an electrical switch. It is used in DC/DC power converters to control the voltage and current levels to achieve desired performance. The device features two low RDS(ON) high-side MOSFETs and two low RDS(ON) low-side MOSFETs which are integrated in a single package. This device has a maximum power point (MPPT) tracking current level that can be programmed for optimal tracking of solar panel output power.

The working principle of FDW9926A is based on the transistor-like behaviour of MOSFETs. The device includes two pairs of transistors connected in parallel, where each pair is referred to as a “phase”. Each phase is driven by a dedicated gate driver circuit. The phase driver generates two square waveforms, one for controlling the voltage and the other for controlling the current. When the gate driver sends a high-level signal to the MOSFETs, they turn on, allowing current to flow through the conduction channels and generating a voltage drop. The voltage drop is then regulated by adjusting the duty cycle and the frequency of the gate driver signals.

The FDW9926A is ideal for applications such as DC/DC converters, solar power, motor control and audio amplifiers. It offers high efficiency, low cost and a wide operating voltage range. The device is verified to meet stringent safety and quality standards that are required in demanding applications. Thanks to the integrated high and low side MOSFETs, the device offers superior power density, making it a preferred choice for high power applications.

In conclusion, the FDW9926A is a high performance two-phase buck controller for DC/DC applications from 4.5V to 64V. It integrates two low RDS(ON) high-side MOSFETs and two low RDS(ON) low-side MOSFETs for optimal power management. The device is based on the transistor-like behaviour of MOSFETs and employs gate driver circuits to generate voltage and current control waveforms. With its high-efficiency, low cost, wide operating range and maximum power point tracking current level, the FDW9926A is an ideal choice for high-power applications.
