The LTC5100EUF#TRPBF is an integrated Laser Driver from Linear Technology Corporation. It is part of their Power Management and Interface (PMIC) product line, specifically for laser drivers. It is a single-chip solution suitable for laser diode drive and thermal management applications in multiple arenas. It is designed to enable a variety of solutions, such as optical communications and medical imaging or range-finding devices.

The LTC5100EUF#TRPBF is capable of delivering up to 5A peak current and up to 85% efficiency. It is specifically designed to interact with laser diodes, allowing regulation of temperature and current and protection against over-voltage or over-temperature conditions, as well as laser diode switching.It can also monitor laser diode health with minimal part count.

The LTC5100EUF#TRPBF is available in a thermally enhanced 20-pin, 4 mm × 3 mm QFN measuring package. It is designed to save power and occupy minimal space, with a 48-V input and a 12-V output. The duty cycle can be adjusted from 0-100%. It features internal soft-start, protection against under-voltage lockout, and over-temperature (OT) protection, as well as a logic-controlled power shutdown.

The LTC5100EUF#TRPBF is designed to operate at temperatures from –40°C to +125°C, making it suitable for industrial and automotive use. It is rated to have a typical quiescent current of only 90 μA. The LTC5100EUF#TRPBF has an integrated, low-noise voltage regulator, allowing the device to be used in a wide range of applications. The integrated 4.5-V to 12-V DC-to-DC converter provides adjustable output current and voltage.

The LTC5100EUF#TRPBF is designed to provide accurate high-speed, high-efficiency laser diode drive. It employs a synchronous flyback topology with integrated power MOSFETs (Metal-Oxide Semiconductor Field-Effect Transistors) to produce pulse width modulated (PWM) laser diode current control with selectable peaking levels. The output current and peak current levels are adjustable in 1-mA increments.

The LTC5100EUF#TRPBF provides instant dynamic response to laser diode current variations. It has the flexibility to comply with a wide range of laser diode drivers and reduce the time needed to integrate a number of laser driver ICs into the same design. This IC integrates the power device, gate driver, and pulse-width modulator on one chip, resulting in fewer components and lower cost.

The LTC5100EUF#TRPBF is part of a complete system-level solution for laser diode drive and thermal management applications. It features fast transient response times, good thermal performance, and high accuracy, making it an ideal choice for laser applications requiring broad temperature ranges.
