Help with TL494pwm !!!!

[Alian]

HI for all Iwant to build swich mode power supply with Full bridge design using irfp460 (4 transistors) and TL494 pwm And ferrite core ETD54 n27 frequency 80Khz And with current adjustable and I want the circuit without driver transformer for mosfet Gate Please any one help me for build the circuit(without driver transformer)!!!!!!!!!!!!!!!!!!!!!!!!!!!

use two tlp250 mosfet on high side and low side drive it through tl494

thankyou very much please if do you can to put circuit diagram to clear this idea

here iam having inverter schematic in the o/p stage tl 494 is used to drive full bridgefor smps you should use 2 tlp250 at tl494 o/p stage
