ST L6902 Up to 1 A switching regulator with adjustable current limit handbook
The L6902D is a complete and simple step down switching regulator with adjustable current limit. Based on a voltage mode structure it integrates a current error amplifier to have a constant voltage and constant current control. By means of an on board current sense resistor and the availability of the current sense pins (both compatible to Vcc and for Cs- compatible with GND too) a current limit programming is very simple and accurate (±5%). Moreover constant current control can be used to charge NiMH and NiCd batteries. The device can be used as a standard DC/DC converter with adjustable current limit (set by using the external sense resistor). The internal robust P-channel DMOS transistor with a typical of 250 mΩ assures high efficiency.
ST L5970D Up to 1A step down switching regulator handbook
The L5970D is a step-down switching regulator capable of delivering up to 1A output current and operating input voltage range from 4.4V to 36V.
