Webaround 50–300 kHz. An integrated circuit such as the TL5001 or TL494 is commonly used to control the transistors at this switching rate. This IC not only controls the switching speed of the transistors, but also controls the conduction time of each transistor. This pulse-width modulation (PWM) sets the on and off duty cycle of the devices. WebSMPS output DAC53204, DAC43204, DAC53004 Objective: Provide a margin voltage for an SMPS output of ±10% the nominal value Design Description This circuit uses a four-channel buffered voltage output DAC to voltage margin a switch-mode power supply (SMPS). A voltage margining circuit is used to trim, scale, or test the output of a power converter.
