MAX20010C/MAX20010D Automotive Single 6A Step-Down Converters General Description Benefits and Features The MAX20010C/MAX20010D ICs are high-efficiency, Fully Integrated, Synchronous 6A DC-DC Converter synchronous step-down converters that operate with a Enables Small Solution Size 3.0V to 5.5V input voltage range and provide a 0.5V to 3.0V to 5.5V Operating Supply Voltage 1.5875V output voltage range. The wide input/output High-Precision Voltage Regulator for Applications voltage range and the ability to provide up to 6A load Processors current make these ICs ideal for on-board point-of-load 2% Output-Voltage Accuracy and post-regulation applications. The ICs achieve 2% Differential Remote Voltage Sensing output error over load, line, and temperature ranges. The 2 I C-Controlled Output Voltage of 0.5V to 1.27V MAX20010D offers improved transient response. in 10mV Steps, or 0.625V to 1.5875V in The ICs feature a 2.2MHz fixed-frequency PWM mode 12.5mV Steps Excellent Load-Transient Performance for better noise immunity and load-transient response, and a pulse-frequency modulation mode (skip) for Low-Noise Feature Reduces EMI increased efficiency during light-load operation. The 2.2MHz Operation 2.2MHz frequency operation allows the use of all-ceramic Spread-Spectrum Option capacitors and minimizes the solution footprint. The Frequency-Synchronization Input/Output programmable spread-spectrum frequency modulation Current-Mode, Forced-PWM, and Skip Operation minimizes radiated electromagnetic emissions. Integrated Robust for the Automotive Environment low R switches improve efficiency at heavy loads DS(ON) PGOOD Output and make the layout a much simpler task with respect to Overtemperature and Short-Circuit Protection discrete solutions. 20-Pin (4mm x 4mm) TQFN with an Exposed Pad The ICs are offered with factory-preset output voltages -40C to +125C Operating Temperature Range 2 (see the Ordering Information for options). The I C inter- AECQ-100 Qualified face supports dynamic voltage adjustment with program- mable slew rates. Other features include programmable Ordering Information appears at end of data sheet. soft-start, overcurrent, and overtemperature protections.
