Description :

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.

Features :

1. Qualified following the AEC-Q100 requirements

2. Up to 1 A DC output current

3. Operating input voltage from 8 V to 36 V

4. Output voltage adjustable from 1.235 V to 35 V

5. Precise 3.3 V (±2 %) reference voltage

6. 250 kHz Internally fixed frequency

7. Voltage feedforward

8. Zero-load current operation

9. Internal current limiting

10. Protection against feedback disconnection

11. Thermal shutdown

Applications :

1. Automotive applications

2. Adjustable current generator

3. Simple step-down converters with adjustable current limit […]
