LT8300IS5#WTRMPBF

Overview

The LT8300IS5#WTRMPBF is a high voltage flyback switching regulator IC manufactured by Analog Devices Inc. It operates with an input voltage range from 6V to 100V and provides a single isolated output capable of up to 260mA switch current. The device supports adjustable output voltages up to 150V and features a wide switching frequency range of 7.5kHz to 750kHz. It is qualified for automotive applications under AEC-Q100 standards and functions within a junction temperature range of -40°C to 125°C.

Feature Summary

Integrated high-voltage startup circuit enables operation from inputs as low as 6V without external bias winding
Supports isolated positive or negative output configurations via standard flyback topology
Automotive-grade qualification ensures reliability in demanding thermal environments

Applications

Industrial power supplies requiring galvanic isolation
Automotive electronics systems operating on high-voltage bus lines
Battery-powered equipment needing efficient step-down conversion

Procurement Notes

Verify the specific suffix WTRMPBF against official Analog Devices documentation to confirm tape-and-reel packaging and industrial temperature grade. Confirm AEC-Q100 compliance status directly with the manufacturer, as availability may be subject to limited supply constraints. Ensure design compatibility with the TSOT-23-5 package dimensions before finalizing procurement orders.

Selection Notes

Select this component when designing isolated DC-DC converters requiring input voltages up to 100V. The integrated startup circuit simplifies design by eliminating the need for auxiliary windings. Consider the 260mA switch current limit for load requirements and ensure the selected switching frequency aligns with transformer specifications for optimal efficiency.

Part Context

This part belongs to the LT8300 series of high voltage flyback controllers. It shares architectural similarities with other members like the LT8301 but differs in specific pinout and feature sets. The IS5 designation indicates the industrial temperature range and TSOT-23-5 package variant, distinguishing it from commercial or larger package options within the same family.
