NXP Semiconductors 33730
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.| Part No. | 33730 |
