Infineon TLD Series DC/DC Controller, 4.5 to 45V Input Voltage, 90mA Maximum Output Current - TLD5099EPXUMA1

This dc/dc controller is a multitopology regulator intended for automotive and industrial power-management applications. It accepts a broad input range and provides a narrow regulated output suitable for downstream electronics while operating across extended ambient temperatures. The device is supplied in a Compact surface-mount package for board-level integration and is designed to meet automotive stress qualifications and environmental restrictions.

Features and Benefits:

• 4.5 to 45V input range enables wide-voltage source compatibility
• 4.85 to 5.15V regulated output ensures stable supply for loads
• 90mA maximum output current supports small power rails
• 500kHz switching frequency reduces external component size
• 3mA supply current minimises quiescent power draw

Applications

• Suitable for in-vehicle auxiliary power rails
• Ideal for Compact industrial control modules
• Used with sensor clusters requiring regulated 5V
• Can be used for low-power communications circuitry

What thermal range can it operate within?

It functions between -40°C and 150°C allowing use in high-temperature environments.

What package and mounting type does it use?

It is supplied in a 14-pin PG-TSDSO-14 package designed for surface mounting.

How does its topology flexibility benefit designs?

The multitopology architecture supports different DC-DC configurations to accommodate varied conversion needs.

Which regulatory and automotive standards apply?

It conforms to RoHS restrictions and meets the AEC-Q100 automotive qualification.

What is the maximum duty cycle during operation?

The device is specified to operate up to a 91% duty cycle.
