KIT33730EKEVBE

The KIT33730EKEVBE is an evaluation module for 33730, switch mode power supply with multiple linear regulators. The 33730 is a multiple output power supply integrated circuit 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 (typ) 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. The linear regulators can be configured either as two normal mode regulators (VDD3, VDDL) and one standby regulator (VKAM), or as one normal mode linear regulator (VDDL) and two standby regulators (VKAM and VDD3 Standby). Two protected outputs [VREF (1, 2)] are used to provide power to external sensors.
