DC DC Converters become increasingly popular in automotive, computer, and telecommunications products. The PT4667N is a high-performance switching regulator ideal for applications requiring low-noise, high-efficiency, and fast transient response. Its small size and low cost make it an attractive option for many applications.

The device is based on a full bridge structure to ensure tight control over peak current and very low switching losses. Its soft-switching feature can reduce operating frequency to reduce EMI and power dissipation, especially at light loads. An internally connected Schottky diode is used in each power switch to minimize switching losses.

The PT4667N has wide power input range with a wide range of application solutions. The device can provide output currents up to 3.75 A to meet the requirement of high-current applications. In addition, it can deliver up to 50 W output power due to its high efficiency of up to 95%. The internal PWM controller and MOSFETs optimize the efficiency of the switching regulator throughout.

The PT4667N operates over a wide input voltage range from 7V to 20V and has extremely short start-up times for all input voltages. The device also features an output voltage accuracy of ±2%. This high accuracy and low noise make it ideal for a range of critical, precision, and high-performance applications, such as automotive, audio, LEDs, and CPU/GPU power supplies.

The PT4667N is equipped with a powerful on-chip error amplifier so that it can be configured with a feedback resistor divider without the need for an external error amplifier. And it can achieve output voltage 16V, 18V, and 19V with a single design. The device also features a wide range of protection, including overload, over voltage, under voltage protection, over temperature protection, and short-circuit protection.

In summary, the PT4667N is an ideal choice for applications that require low-noise, high-efficiency, and fast transient response. It offers excellent performance and rich features, as well as a wide power input range and high accuracy output. Furthermore, the device is relatively small and affordable, making it an attractive choice for many applications.
