Key Features
- Wide 3.6 V to 40 V input range accommodates automotive 12 V/24 V battery rails, 28 V avionics bus, and industrial 24 V supplies in a single controller
- 500 kHz fixed switching frequency allows compact magnetics design with inductors below 10 µH for space-constrained automotive converter modules
- AEC-Q100-qualified for -40°C to +125°C operation ensures reliable performance in underhood and dashboard automotive environments
Applications
The TL5001AQDG4 is used in automotive body electronics, instrument cluster power supplies, and industrial 24 V rail-to-regulated-output DC-DC converters where a wide input voltage swing and AEC-Q100 qualification are mandatory. Its voltage-mode PWM architecture supports both step-down and step-up converter topologies, making it versatile for powering 5 V or 3.3 V rails from 12 V automotive batteries or boosting low-voltage inputs to higher bus voltages in motor and lighting control modules.

Frequently Asked Questions
What input voltage range does TL5001AQDG4 support, and which automotive bus standards does this cover?
TL5001AQDG4 accepts 3.6 V to 40 V on its input, covering standard 12 V automotive batteries (9 V to 16 V), 24 V truck and commercial vehicle buses (16 V to 32 V), and load-dump transient conditions up to 40 V as specified by ISO 16750-2. This eliminates the need for an external clamp circuit in most automotive converter designs.
How does the 500 kHz switching frequency affect inductor selection in a TL5001AQDG4 step-down converter?
At 500 kHz, the minimum inductor value for a 12 V to 5 V, 1 A buck converter is approximately 7 µH using L_min = (V_in - V_out) × D / (f_sw × ΔI_L), where ΔI_L is 30% of I_out. A 10 µH, 1.5 A rated inductor in a 2.5 mm × 2.5 mm footprint is practical, reducing the overall converter size versus designs running at 100 kHz to 200 kHz.
Is TL5001AQDG4 qualified for automotive use, and what reliability tests does this imply?
Yes, the TL5001AQDG4 carries AEC-Q100 Grade 1 qualification, requiring operating life tests at 125°C junction temperature, ESD withstand of HBM ±2 kV and CDM ±500 V, HTOL at 125°C for 1,000 hours, and temperature cycling from -55°C to +150°C for 1,000 cycles. These qualifications allow direct use in Tier-1 automotive supply chains without additional component-level screening.
