Product Overview

The MAX20022ATIA/V+ from Maxim Integrated Products is an Automotive quad, low-voltage step-down DC to DC converter in 28 pin TQFN-EP package. This power-management IC (PMIC) integrates four low-voltage, high-efficiency, step-down DC to DC converters. Adjustable output-voltage can be set to any desired values between 1.0V and 4.0V using an external resistive divider. It features fixed-frequency PWM-mode operation with a switching frequency of 2.2MHz. The low-resistance on-chip switches ensure high efficiency at heavy loads while minimizing critical inductances, making the layout a much simpler task with respect to discrete solutions. Two of four buck converters operate 180° out-of-phase with the internal clock. This feature reduces the necessary input capacitance and improves EMI as well. All four buck converters operate in constant-PWM mode outside the AM band. It offers a SYNC input to synchronize to an external clock.
  • Operates from 3V to 5.5V makes it ideal for automotive point-of-load and post regulation application
  • Current configuration is 1A(CH1, CH2, CH3, CH4)
  • Output voltage is Adjustable
  • Active time out period is 256cycles
  • Individual enable inputs and power-good outputs to simplify sequencing
  • Input overvoltage protection, undervoltage lockout, overtemperature shutdown
  • Cycle-by-cycle current limiting
  • Soft-start and supply sequencing reduces inrush current
  • Internal current sensing and loop compensation reduce board space and system cost
  • Operating temperature range from -40°C to +125°C
