TEA1501T/N1,118

 Introduction of TEA1501T/N1,118

The TEA1501T/N1,118 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 TEA1501T/N1,118

•  Q: What is the difference between TEA1501T/N1,118 and TEA1501T/N1,518?

•  A: The TEA1501T/N1,118 and the TEA1501T/N1,518 have the same specifications and features, except for the package type. The TEA1501T/N1,118 has a SO14 package, while the TEA1501T/N1,518 has a SO14 package with dry pack.

•  Q: What is the difference between TEA1501T/N1,118 and TEA1501AT/N1,118?

•  A: The TEA1501T/N1,118 and the TEA1501AT/N1,118 have the same specifications and features, except for the overvoltage protection mode. The TEA1501T/N1,118 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 TEA1501AT/N1,118 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 TEA1501T/N1,118 development?

•  A: You can use the GreenChip™II SMPS control IC development kit, which includes the TEA1501T/N1,118 device, a development board, a power supply, cables, and software tools.
