Switch Mode Power Supply with Multiple Linear Regulators
The 33730 is a multiple output power supply integrated circuit for automotive applications. The integrated circuit (IC) incorporates a switching regulator, which operates over a wide input voltage range from 4.5 to 26.5 V.
The step-down switching regulator uses a fixed frequency pulsewidth modulation (PWM) voltage mode control. It has a 3.5 A current limit (typical) and the slew-rate is adjustable via a control pin to reduce switching noise. The switching regulator has an adjustable frequency oscillator, which allows the user to optimize...
