"INNOVATORS IN MAGNETICS TECHNOLOGY" – Magnetics Micro Linear's ML4824 Switcher — Magnetics For Micro Linear's Ballast IC's GENERAL APPLICATION ML4824-1 SCHEMATIC Premier Magnetics' TSD-735 Switch Mode Transformer was designed for use with MICRO LINEAR'S ML4824-1 PFC/PWM Combination off-line controller IC, in the Two Transistor Single-Ended Forward Converter Configuration. This converter topology can provide isolated multiple outputs with efficiencies up to 90%. Premiers' TSD-735 transformer has been optimized to provide maximum power throughput and to provide the necessary bias voltage for the ML4824-1 and it's auxiliary circuitry. The ML4824-1 from Micro Linear is highly integrated power supply controller, incorporating a PFC front end operating at 100KHz, and a synchronized PWM switching regulator running @ 50KHz. This combination provides all necessary functions for a Universal-Input, Power Factor Corrected DC power supply in the 50 to 500W output range. The TSD- 734 boost inductor and TSD-735 output transformer are critical to the performance of the circuit. Together they define the harmonic reduction, efficiency, output power and the size of the Power Factor Correction and DC output stages. Below is a typical universal input, high precision application circuit utilizing Micro Linear's ML4824-1 PFC/PWM control IC. The AC mains voltage is power factor corrected and boosted to 382VDC by the PFC half of the ML4824-1 and the TSD-734 PFC boost inductor. The PWM half of the ML4824-1 and the PMGD-03 gate drive transformer then provide the MOSFET gate drives for operating the TSD-735 output transformer which converts the 382VDC hot rail to a regulated 12VDC, 100W output. Recommended component values can be obtained from Micro-Linear's ML4824- 1 application notes. Evaluation boards are available from Micro Linear.
