UC2844BDR2G Product Details

Product Description:

The UC2844BDR2G is a surface-mount, switching controller IC designed by ON Semiconductor. This analog IC is a part of the PMIC family, specifically designed for voltage regulators and DC-DC switching controllers. It is a current-mode, pulse-width modulation (PWM) controller that operates in a step-up or step-up/step-down configuration.

Features:

  • Frequency Control: The UC2844BDR2G features frequency control, allowing for precise control over the switching frequency.
  • Current-Mode Operation: The IC operates in current-mode, providing high efficiency and low noise.
  • Pulse Width Modulation: The controller uses PWM to regulate the output voltage.
  • Step-Up and Step-Up/Step-Down Operation: The IC can be used for both step-up and step-up/step-down applications.
  • Halogen-Free and Lead-Free: The product is designed with environmental sustainability in mind, being halogen-free and lead-free.
  • Compact Package: The IC is available in a 14-pin SOIC package, making it ideal for space-constrained applications.

Applications:

  • Primary Applications: The UC2844BDR2G is suitable for use in DC-DC converters, such as those found in power supplies, telecommunications equipment, and industrial control systems.
  • Secondary Applications: The IC can also be used in other applications where a high-frequency, high-efficiency switching controller is required, such as in audio equipment, medical devices, and automotive systems.

Ya good and arrive on time. thank you so much
BenjaminReed
he Capacitance box works great and exactly how I expected it to, but the design of the Resistance & Inductance boxes is very different and requires reading the datasheet to understand how they are supposed to work.
Russell
no complaints so far.
Fox
Pricing was moderate, reflecting standard market rates.
Morla
They have a wide selection of products and competitive prices. Despite some minor issues, their customer service team solved my problem and maintained good communication.
