Thanks to Texas Instruments, you can now modulate the voltage entering your circuit using their SG2524DR voltage mode PWM controller. Its 2 PWM outputs produce a current of 100(Max) mA. This voltage mode driver supports boost|buck|flyback|forward|full-bridge|half-bridge|push-pull topology. Its switching regulator has a frequency of 450(Typ) kHz. 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 -25 В°C to 85 В°C. This voltage mode driver&s;s maximum duty cycle is 45(Min) %. This device has a minimum operating supply voltage of 8 V and a maximum of 40 V.
