TNY276GN-TL Integrated Circuits (ICs)

Power management integrated circuits, or PMICs, are found at the heart of most electronic systems. Often, the most important part of the PMIC is its ability to convert one form of electrical energy into another. AC/DC converters and offline switchers are two key components of this process. TNY276GN-TL is an integrated offline switcher from Taiwanese manufacturer TracoPower that offers higher efficiency, improved design flexibility, and lower system cost compared to previous devices.

The TNY276GN-TL integrates the drive, control, and power FETs for antiphase operation inside a 3-pin SIP (small-outline integrated circuit) package, making it easier to design. Its feature set includes wide input voltage range from 75V AC to 305V AC, plus constant-current or constant-voltage output options. The device provides efficient regulation with low output ripple and very low standby power consumption, meeting the needs of a wide range of applications. Its off-time control feature reduces inrush current during start-up.

The TNY276GN-TL takes a step towards simplifying the design of LAN, audio and industrial SMPS (switched-mode power supplies), optimized for low cost. It features integrated soft start, priority control logic, and under-voltage lockout (UVLO). The device is cost-sensitive, with a host of features developed specifically for high performance and low cost. The thermal protection and over-current protection features ensure reliable operation in harsh electrical and environmental conditions.

TNY276GN-TL is a highly integrated solution that makes AC/DC offline switcher design easier for applications such as batteries, gate drivers, telecom, automotive electronics, and industrial applications. The device offers industry-leading performance and high electrical efficiency, along with increased design flexibility and reduced system cost compared to previous generations.

The TNY276GN-TL is based on NMOS technology and has a switching frequency of up to 500kHz. It uses an innovative burst mode operation to reduce no-load power consumption. The device’s built-in PFC (power factor correction) provides up to 99 percent efficiency, allowing it to meet the stringent energy efficiency requirements of various standards and regulations. Its highly efficient design also allows it to operate in hot and cold ambient temperatures, thanks to its very low start-up current.

As the demand for high efficiency, low cost, and small form factor continues to rise, integrated offline switchers like TNY276GN-TL will remain important in power management design. This device is optimized for ease of use and cost-effectiveness, with a variety of features developed to meet end user needs.
