250W hybrid planar transformers only 16.51mm high

December 12, 2016 // By Julien Happich
Vishay Intertechnology's TPL-2516 series of 250W full-bridge hybrid planar transformers are designed for avionics, industrial control, and alternative energy control applications.

Featuring a unique winding structure that allows for a greater copper fill factor than traditional planar transformers, the units come in smaller overall package sizes, a low 16.51 mm maximum profile, and with higher power density levels. The unique winding technology also allows the parts to be easily and quickly modified for custom voltage / power applications with no upfront tooling charges to the customer. Featuring a split primary design for efficient 120 V or 380 V operation, TPL-2516 series transformers are optimized for offline and PFC-derived switchmode power supplies and full-bridge / half-bridge converters. Designed to meet MIL-PRF-27 requirements, the devices feature overmolded windings for rugged applications and are environmentally sealed for operation in harsh environments. The TPL-2516 series features operating frequencies from 100 kHz to 500 kHz, power dissipation of 3 W, rated current to 22.0A, leakage inductance down to 1.30 µH, and minimal parasitic variation. The devices offer a temperature range of -55 °C to +130 °C, with power derating above +105 °C. Samples and production quantities of the TPL-2516 series are available now, with lead times of eight to 10 weeks.
