The MAX16962 is a high-efficiency, 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 wide input/output voltage range and the ability to provide up to 4A to load current make this device ideal for on-board point-of-load and post-regulation applications. The MAX16962 achieves -3.7%/+2.6% output error over load, line, and temperature ranges.
The MAX16962 features a 2.2MHz fixed-frequency PWM mode for better noise immunity and load transient response, and a pulse frequency modulation mode (SKIP) for increased efficiency during light-load operation. The 2.2MHz frequency operation allows for the use of all-ceramic capacitors and minimizes external components. The optional spread-spectrum frequency modulation minimizes radiated electromagnetic emissions.
Integrated low RDSON switches improve efficiency at heavy loads and make the layout a much simpler task with respect to discrete solutions.
The MAX16962 is offered with factory-preset output voltages or with an adjustable output voltage. Factory-preset output voltage versions allow customers to achieve -3.7%/+2.6% 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 to 3.6V using an external resistive divider.
Additional features include 8ms soft-start, 16ms power-good output delay, overcurrent, and overtemperature protections.
The MAX16962 is available in thermally enhanced 16-pin TSSOP-EP and 4mm x 4mm, 16-pin TQFN-EP packages, and is specified for operation over the -40°C to +125°C automotive temperature range.
