MAX8744A規(guī)格書詳情
General Description
The MAX8744A/MAX8745A are dual step-down, switch mode, power-supply (SMPS) controllers with synchronous rectification, intended for main 5V/3.3V power generation in battery-powered systems. Fixed-frequency operation with optimal interleaving minimizes input rip ple 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 regulators where the duty-cycle overlap occurs when the input drops below 10V.
Features
? Fixed-Frequency, Current-Mode Control
? 40/60 Optimal Interleaving
? Internal BST Switches
? Internal 5V, 100mA Linear Regulator
? Auxiliary Linear-Regulator Driver (12V or Adjustable Down to 1V)
? Dual Mode? Feedback—3.3V/5V Fixed or Adjustable Output Voltages
? 200kHz/300kHz/500kHz Switching Frequency
? Undervoltage and Thermal-Fault Protection
? Overvoltage-Fault Protection (MAX8744A Only)
? 6V to 26V Input Range
? 2V ±0.75 Reference Output
? Independent Enable Inputs and Power-Good Outputs
? Soft-Start and Soft-Shutdown (Voltage Ramp)
? 8μA (typ) Shutdown Current
