KTD2511CEHD-TR

Overview

The KTD2511CEHD-TR is a wide-range PWM dimming boost converter IC designed for LED applications, featuring a 19V overvoltage protection (OVP) rating. It operates within an input voltage range of 2.7 V to 5.5 V and delivers a constant output current of 260 mA. The device utilizes a Boost topology with a switching frequency of 1 MHz and supports up to three or five series LEDs. Packaged in a TSOT-23-6 surface-mount format, it functions across a temperature range of -40°C to +85°C.

Feature Summary

• Integrated high-efficiency PWM control for precise brightness adjustment
• Built-in overvoltage protection rated at 19V to safeguard connected loads
• Compact TSOT-23-6 package design suitable for space-constrained PCB layouts

Applications

• Portable LED lighting systems requiring wide-range dimming
• Battery-powered illumination devices utilizing single-cell power sources
• General-purpose constant current LED driver circuits

Procurement Notes

Verify the specific suffix against official Kinetic Technologies documentation to confirm pinout compatibility and electrical ratings. Ensure the ordering code matches the required OVP threshold and packaging type. Cross-reference the manufacturer's latest datasheet to validate RoHS compliance status and operating temperature specifications before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require a compact boost solution for low-voltage inputs driving multiple series LEDs. The integrated switch eliminates external inductor requirements in some configurations, simplifying BOM. Consider the 260 mA output limit and 19V OVP ceiling to ensure alignment with target LED string voltage and current demands.

Part Context

This part belongs to the Kinetic Technologies KTD251x family of LED drivers. It shares architectural similarities with other members like the KTD2511 but differs in voltage ratings and switch capabilities compared to variants such as the KTD2511CEHD-TR. The family focuses on efficient, small-footprint solutions for portable lighting markets.

Replacement Considerations

Direct substitutes include other parts from the KTD251x series with matching pinouts and similar electrical characteristics. Verify functional equivalence regarding PWM dimming behavior and OVP levels before swapping components in existing designs.
