Infineon releases IFX90121 is a high-frequency PWM step-down DC/DC converter with an integrated PMOS power switch, packaged in a small PG-SSOP-14 with exposed pad.
This 5 V, 500 mA, 2.2 MHz integrated buck converter offers wide input voltage and operating temperature ranges. The input voltage ranges from 4.75 to 45 V , making it the perfect fit for many different industrial applications. The switching frequency of nominal 2.2 MHz allows small and cost-effective inductors and capacitors to be used, resulting in a low, predictable output voltage ripple and board space savings.
