TEA1623PH/N1,112

Introduction of TEA1623PH/N1,112

The TEA1623PH/N1,112 is a Switched Mode Power Supply (SMPS) control IC that belongs to the STARplug™ 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 TEA1623PH/N1,112

•  Q: What is the difference between TEA1623PH/N1,112 and TEA1623P/N1,112?

•  A: The TEA1623PH/N1,112 and the TEA1623P/N1,112 have the same specifications and features, except for the overvoltage protection mode. The TEA1623PH/N1,112 has a safe restart mode, which means that the device will try to restart automatically after an overvoltage fault, without cycling the mains supply. The TEA1623P/N1,112 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.

•  Q: How can I get started with the TEA1623PH/N1,112 development?

•  A: You can use the STARplug™ SMPS control IC development kit, which includes the TEA1623PH/N1,112 device, a development board, a power supply, cables, and software tools.
