TEA1553T/N1,518

 Introduction of TEA1553T/N1,518

The TEA1553T/N1,518 is a Switched Mode Power Supply (SMPS) control IC that belongs to the GreenChip™ II series, which offers high efficiency, low power consumption, and flexible programmability for a wide range of applications. It is manufactured by NXP and operates directly from the rectified universal mains. It supports valley or zero voltage switching for minimum switching losses, efficient quasi-resonant operation at high power levels, frequency reduction at low power standby, and cycle skipping mode at very low loads. It also provides various protection features, such as safe restart mode, continuous mode protection, overvoltage protection, short winding protection, undervoltage protection, overtemperature protection, and overcurrent protection. It has a high level of integration, giving a very low external component count.

 Frequently Asked Questions of TEA1553T/N1,518

•  Q: What is the difference between TEA1553T/N1,518 and TEA1553T/N1/G,518?

•  A: The TEA1553T/N1,518 and the TEA1553T/N1/G,518 have the same specifications and features, except for the overvoltage protection mode. The TEA1553T/N1,518 has a latched mode, which means that the device will shut down permanently after an overvoltage fault, and needs to be restarted by cycling the mains supply. The TEA1553T/N1/G,518 has a safe restart mode, which means that the device will try to restart automatically after an overvoltage fault, without cycling the mains supply.

•  Q: How can I get started with the TEA1553T/N1,518 development?

•  A: You can use the GreenChip™ II SMPS control IC development kit, which includes the TEA1553T/N1,518 device, a development board, a power supply, cables, and software tools.
