Manufacturer:INFINEO Description:The MAX1533/MAX1537 are dual step-down, switch- mode power-supply (SMPS) controllers with synchro- nous rectification, intended for main 5V/3.3V power generation in battery-powered systems. Fixed-frequen- cy operation with optimal interleaving minimizes input ripple current from the lowest input voltages up to the 26V maximum input. Optimal 40/60 interleaving allows the input voltage to go down to 8.3V before duty-cycle overlap occurs, compared to 180 out-of-phase regula- tors where the duty-cycle overlap occurs when the input drops below 10V. Output current sensing pro- vides accurate current limit using a sense resistor. Alternatively, power dissipation can be reduced using lossless inductor current sensing. Internal 5V and 3.3V linear regulators power the MAX1533/MAX1537 and their gate drivers, as well as external keep-alive loads, up to a total of 100mA. When the main PWM regulators are in regulation, automatic bootstrap switches bypass the internal linear regulators, providing currents up to 200mA from each linear output. An additional 5V to 23V adjustable internal 150mA linear regulator is typically used with a secondary winding to provide a 12V supply. |
