The NXP® MCZ33730EK is a multiple output power supply integrated circuit that incorporates a switching regulator with an adjustable frequency oscillator for automotive applications.
- The integrated circuit incorporates a switching regulator which operates over a wide input voltage range from +4.5V to +26.5V
- The step-down switching regulator uses a fixed frequency PWM voltage mode control
- It has a 3.5A 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 its operation over a wide range of input voltages and component values
