AN33016UA - Buck DC-DC Controller, 5V-39V Input, 1.5A Output, 2MHz Switching Frequency, SSOP-24 for Automotive Instrument Cluster Backlight
This product is a highly versatile PWM step-down DC-DC controller designed for a wide range of power regulation applications. It operates within a broad input voltage range of 5V to 39V, making it suitable for various automotive and industrial power systems. The device provides an adjustable output voltage from 1.2V up to 35V, offering great flexibility for different circuit designs.
The controller supports a high switching frequency of up to 2MHz. This high-frequency operation allows for the use of smaller external inductors and capacitors, which helps to reduce the overall footprint on your PCB. It is an ideal solution for space-constrained applications like modern automotive instrument clusters and infotainment displays.
This IC delivers a maximum output current of 1.5A, providing sufficient power for driving LED backlights and other critical subsystems. It integrates essential control features, including an enable pin, frequency control, and a soft-start function. The soft-start feature is particularly useful for limiting inrush current during power-up, enhancing system reliability.
Housed in a compact 24-pin SSOP package, the chip measures just 7.8mm x 6.1mm. This small outline package is optimized for surface-mount assembly, making it suitable for high-volume manufacturing. The device supports clock synchronization, which is a critical feature for noise-sensitive applications as it helps to manage and reduce electromagnetic interference (EMI).
Designed to perform reliably in harsh environments, this controller operates over an extended temperature range of -40°C to +85°C. This ensures stable performance under extreme conditions commonly found in automotive engine bays or outdoor industrial equipment. It is fully compliant with RoHS environmental standards.
This controller is suitable for a wide variety of step-down (buck) converter designs. Typical applications include power supplies for microcontrollers, memory, and other digital logic circuits. It is also an excellent choice for powering LED driver circuits and other general-purpose DC-DC conversion tasks.
