Description

General part information

MAX20020 Series

MAX20019/MAX20020 are 2.2MHz and 3.2MHz dual step-down converters with integrated high-side and low-side MOSFETs. The high-voltage step-down converter is designed for continuous operation up to 17V input voltages. The output voltage is factory preset. Buck 1 is preset to 3.3V, 3.0V, or 2.8V. Buck 2 is preset to 1.8V, 1.5V, 1.2V, or 1V. Another option is Buck 1 preset to 5V and Buck 2 preset to 3.3V.The low-voltage buck features fixed-frequency PWM- mode operation with a switching frequency of 2.2MHz or 3.2MHz. High-frequency operation allows for an all-ceramic capacitor design and small-size external components. The low-resistance on-chip switches ensure high efficiency while minimizing critical inductance. A 500mV enable hysteresis on the MAX20019 allows the use of long, low-cost coax cables, even during slow startup situations. The MAX20020’s Buck 1 starts after VSUPis greater than 5.5V and Buck 1 is driven by the EN input.Protection features include overvoltage (OV) protection, cycle-by-cycle current limit, and thermal shutdown with automatic recovery. The buck converters operate 180° out-of-phase from each other to minimize input-current ripple.Design Solution: Provide a Safe Power Path from the Car Battery to Remote Cameras ›Design Solution: How to Miniaturize Your Automotive Remote Camera ›ApplicationsAutomotive Point-of-LoadSurround-View Camera Power Supplies
