概述
Description
LT1910IS8#PBF is the Pb-free, 8-pin MSOP package variant of Linear Technology’s LT1910 switching regulator controller. It is a PWM controller intended to drive an external power stage (FET, inductor, diode) to implement DC-DC conversions (buck, boost, or buck-boost) with high efficiency. Key features typically include current-mode control, soft-start, enable/shutdown, adjustable output via feedback, and protections such as over/under-voltage, current limit, and thermal shutdown. The IS8 suffix identifies the MSOP-8 package, and #PBF denotes Pb-free packaging. Use it in compact power-supply designs where an external power stage is acceptable.
Features
LT1910IS8#PBF features (concise):
- High-voltage LED driver/controller in an 8-pin Pb-free package
- Wide input range (up to about 60–75V)
- External N-channel MOSFET drive; current-mode regulation
- Programmable constant-current LED drive via sense resistor
- Open-LED protection and robust short-circuit protection (hiccup)
- Overvoltage/undervoltage lockout and thermal shutdown
- Dimming support (PWM and/or DC-dimming inputs)
- High efficiency and compact solution for automotive/industrial lighting
Note: Exact numbers can vary by revision; verify with the latest datasheet.
