Sales Briefcase
  • The A6902D is a complete step down switching regulator with adjustable current limit. Based on a voltage mode structure it integrates an additional current error amplifier to implement both a constant voltage and constant current control.

    The current limit programming is very simple and accurate (± 5%) selecting the proper sensing resistor.
    The internal P-Channel DMOS transistor (typ. RDSON 250 mΩ) assures high efficiency and minimum dropout even at high output current level.

    Key Features

    • Qualified following the AEC-Q100 requirements
    • Up to 1 A DC output current
    • Operating input voltage from 8 V to 36 V
    • Output voltage adjustable from 1.235 V to 35 V
    • Precise 3.3 V (±2 %) reference voltage
    • 250 kHz Internally fixed frequency
    • Voltage feedforward
    • Zero-load current operation
    • Internal current limiting
    • Protection against feedback disconnection
    • Thermal shutdown
