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 and a minimum dropout even at high output current level. The internal limiting current (latched function) of typical value of 2.5 A protects the device from accidental output short circuit avoiding dangerous loads damage. If the temperature of the chip goes higher than a fixed internal threshold (150°C with 20°C hysteresis), the power stage is turned off. Other protections beside thermal shutdown complete the device for a safe and reliable application: overvoltage protection, frequency folback overcurrent protection and protection vs. feedback disconnection. The internal fixed switching frequency of 250KHz, and the SO-8 package pin allow to built an ultra compact DC/ DC converter with a minimum board space. https://elecena.pl/product/16964228/l6902d013tr-up-to-1-a-switching-regulator-with-adjustable-current-limit 2020-06-12 https://elecena.pl/product/16964228/l6902d013tr-up-to-1-a-switching-regulator-with-adjustable-current-limit 2021-04-03 https://elecena.pl/product/16964228/l6902d013tr-up-to-1-a-switching-regulator-with-adjustable-current-limit 2021-04-15 https://elecena.pl/product/16964228/l6902d013tr-up-to-1-a-switching-regulator-with-adjustable-current-limit 2021-07-16 https://elecena.pl/product/16964228/l6902d013tr-up-to-1-a-switching-regulator-with-adjustable-current-limit 2021-12-04 https://elecena.pl/product/16964228/l6902d013tr-up-to-1-a-switching-regulator-with-adjustable-current-limit 2022-04-07 https://elecena.pl/product/16964228/l6902d013tr-up-to-1-a-switching-regulator-with-adjustable-current-limit 2022-06-13 https://elecena.pl/product/16964228/l6902d013tr-up-to-1-a-switching-regulator-with-adjustable-current-limit 2022-06-25 https://elecena.pl/product/16964228/l6902d013tr-up-to-1-a-switching-regulator-with-adjustable-current-limit 2023-03-23 https://elecena.pl/product/16964228/l6902d013tr-up-to-1-a-switching-regulator-with-adjustable-current-limit 2023-04-29 https://elecena.pl/product/16964228/l6902d013tr-up-to-1-a-switching-regulator-with-adjustable-current-limit 2023-08-16 https://elecena.pl/product/16964228/l6902d013tr-up-to-1-a-switching-regulator-with-adjustable-current-limit 2024-01-16 https://elecena.pl/product/16964228/l6902d013tr-up-to-1-a-switching-regulator-with-adjustable-current-limit 2024-08-16 https://elecena.pl/product/16964228/l6902d013tr-up-to-1-a-switching-regulator-with-adjustable-current-limit 2024-09-12 https://elecena.pl/product/16964228/l6902d013tr-up-to-1-a-switching-regulator-with-adjustable-current-limit 2024-10-07 https://elecena.pl/product/16964228/l6902d013tr-up-to-1-a-switching-regulator-with-adjustable-current-limit 2024-11-21 https://elecena.pl/product/16964228/l6902d013tr-up-to-1-a-switching-regulator-with-adjustable-current-limit 2024-12-09 https://elecena.pl/product/16964228/l6902d013tr-up-to-1-a-switching-regulator-with-adjustable-current-limit 2025-01-23 https://elecena.pl/product/16964228/l6902d013tr-up-to-1-a-switching-regulator-with-adjustable-current-limit 2025-02-01 https://elecena.pl/product/16964228/l6902d013tr-up-to-1-a-switching-regulator-with-adjustable-current-limit 2025-03-29 https://elecena.pl/product/16964228/l6902d013tr-up-to-1-a-switching-regulator-with-adjustable-current-limit 2025-05-04 https://elecena.pl/product/16964228/l6902d013tr-up-to-1-a-switching-regulator-with-adjustable-current-limit 2025-07-04 https://elecena.pl/product/16964228/l6902d013tr-up-to-1-a-switching-regulator-with-adjustable-current-limit 2026-05-15 https://elecena.pl/product/16964228/l6902d013tr-up-to-1-a-switching-regulator-with-adjustable-current-limit 2026-06-03 https://elecena.pl/product/16964228/l6902d013tr-up-to-1-a-switching-regulator-with-adjustable-current-limit 2026-06-21
