The MAX16963 is a high-efficiency, dual synchronous step-down converter that operates with a 2.7V to 5.5V input voltage range and provides a 0.8V to 3.6V output voltage range. The device delivers up to 1.5A of load current per output. The low input/output voltage range and the ability to provide high output currents make this device ideal for on-board point-of-load and postregulation applications. The device achieves ±3% output error over load, line, and temperature ranges. The device features a 2.2MHz fixed-frequency PWM mode for better noise immunity and load transient response, and a skip mode for increased efficiency during light-load operation. The 2.2MHz frequency operation allows for an all-ceramic capacitor design and small-size external components. An optional spread-spectrum frequency modulation minimizes radiated electromagnetic emissions due to the switching frequency. On-board low RDSON switches help minimize efficiency losses at heavy loads and reduce critical/parasitic inductance, making the layout a much simpler task with respect to discrete solutions. Following a simple layout and footprint ensures first-pass success in new designs. The device is offered in a factory-preset output voltage or adjustable output-voltage version (see the Selector Guide in the full data sheet for options). Factory-preset output-voltage versions allow customers to achieve ±3% output-voltage accuracy without using external resistors, while the adjustable output-voltage version provides the flexibility to set the output voltage to any desired value between 0.8V and 3.6V using an external resistive divider. Additional features include 8ms fixed soft-start, 16ms fixed power-good delay, overcurrent, and overtemperature protections. The MAX16963 is available in thermally enhanced 16-pin TSSOP-EP and 4mm × 4mm, 16-pin TQFN-EP packages, and is specified for operation over the -40°C to +125°C automotive temperature range.
