製品概要

概要

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 DC-DC converter can be used either as a voltage source with adjustable current limit (set by using the external sense resistor) or as current source to charge NiMH / NiCd batteries or drive voltage load like LEDs.

The internal P-Channel DMOS transistor (typ. R_DSON 250 mΩ) assures high efficiency and minimum dropout even at high output current level.
