Description
The A6902D is a plete 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 Ni MH / Ni Cd batteries or drive voltage load like LEDs. The internal P-Channel DMOS transistor (typ. RDSON 250 mΩ) assures high efficiency and minimum dropout even at high output current level.
