Description

LT1910ES8#PBF is an 8‑pin Linear Technology (now Analog Devices) device used as a high‑voltage, constant‑current regulator/LED driver. The ES8 suffix indicates the 8‑lead MSOP package, and PBF means Pb‑free. The IC provides a control loop that senses current (via a sense resistor) and regulates load current, suitable for driving LEDs or other constant‑current loads from a higher supply. It typically requires an external power device (transistor) and external resistors to set the programmable current, with protections such as enable control, current/short‑circuit protection, undervoltage, and thermal shutdown. Applications include automotive lighting, LED backlighting, and compact constant‑current Regulators. For exact pinout, configuration, and electrical specs (input voltage range, current set resistor, protection thresholds, etc.), refer to the LT1910 datasheet on Analog Devices’ website.

Features

LT1910ES8#PBF features (concise):
- High-side load switch with current limit
- 40V maximum input voltage
- Overcurrent protection and thermal shutdown
- Undervoltage lockout
- Reverse-battery protection
- Enable input to turn the switch on/off
- Suitable for automotive use (low quiescent/off-state current)
- Pb-Free, 8-pin SOIC package (ES8)
Note: For exact ratings (current limit, thresholds, quiescent currents), consult the datasheet.

Pinout

- Pin count: 8 pins (ES8 package).
- Function: A high‑voltage PWM controller for switch‑mode power supplies (drives an external MOSFET) with current‑mode control and protection features, used in offline/high‑voltage regulator applications.

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI). The LT1910ES8#PBF is part of the LT line now under ADI (Analog Devices owns Linear Technology).
- Company type: American multinational semiconductor company that designs, manufactures, and sells analog, mixed-signal, and DSP integrated circuits.

Application

LT1910ES8#PBF is a high‑voltage flyback controller in an 8‑pin package used for isolated power supplies. Typical application areas include:
- Off‑line AC‑DC adapters and embedded power bricks
- Isolated DC‑DC converters for telecom, industrial, and medical equipment
- LED lighting drivers with constant‑current regulation
- Battery charging/power management circuits
- General high‑voltage flyback regulator topologies with startup and protection features

Package

LT1910ES8#PBF comes in an 8-pin SOIC (SO-8) package. The #PBF suffix means Pb-free (RoHS compliant).
