Forward Converter Regulator Positive, Isolation Capable Output Step-Up/Step-Down DC-DC Controller IC 16-TSSOP
The LM5025MTC/NOPB is a Pulse Width Modulated (PWM) Controller contains all of the features necessary to implement power converters using the active clamp and reset technique. The device can be configured to control either a P-channel clamp switch or an N-channel clamp switch. With the active clamp technique, higher efficiencies and greater power densities can be realized compared to conventional catch winding or RDC clamp and reset techniques. Two control outputs are provided, the main power switch control (OUT_A) and the active clamp switch control (OUT_B). The active clamp output can be configured for either a specified overlap time (for P-channel switch applications) or a specified deadtime (for N-channel applications). The two internal compound gate drivers parallel both MOS and bipolar devices, providing superior gate drive characteristics.
Look no further! Texas Instruments has the solution to pulse-width modulation with their LM5025MTCX/NOPB voltage mode PWM controller. Its 2 PWM outputs produce a current of 3000|1000 mA. This voltage mode driver supports forward topology. This part offers a switching frequency of 220 kHz in order to work properly. Tape and reel packaging will encase this product during shipment, in order to ensure safe delivery and enable quick mounting of components. This voltage mode driver has an operating temperature range of -40 °C to 125 °C. This voltage mode driver"s maximum duty cycle is 80 %.
