FAQs

What is TEA5170?

The TEA5170 is a GreenChip synchronous rectifier controller IC designed by NXP Semiconductors. It is specifically tailored for use in switched-mode power supply (SMPS) applications, providing efficient control of synchronous rectifiers in secondary-side synchronous rectification topologies.

How Does TEA5170 Work?

The TEA5170 operates by controlling the synchronous rectification process in a power supply, enabling more efficient energy transfer and reduced power losses. It utilizes a control loop to optimize the timing of the synchronous rectifiers, improving overall power conversion efficiency.

How Many Pins does TEA5170 have and What are the Functions of the Pinout Configuration?

The TEA5170 is available in a 20-pin SSOP (Shrink Small Outline Package) package. The pinout configuration includes:

  • CS: Current sense input.
  • FB: Feedback input for the control loop.
  • GND: Ground connection.
  • VCC: Power supply input.
  • IN-, IN+: Inverting and non-inverting inputs for the control loop.
  • DRV1, DRV2: Gate driver outputs for the synchronous rectifiers.
  • BOOT1, BOOT2: Bootstrap voltage outputs for the gate drivers.
  • COMP: Compensation pin for optimizing control loop stability.

What are the Pros and Cons of TEA5170?
