What are the key features of LT8608IDC#TRMPBF?
- 42 V maximum input voltage handles automotive load-dump and industrial 24 V/36 V bus transients
- 1.5 A peak output current with integrated synchronous MOSFETs for high efficiency
- 3 V to 42 V wide input range covers a broad spectrum of power sources
- PWM current-mode control with fast transient response for dynamic loads
- Compact 8-lead DFN package minimizes PCB footprint in dense power modules
- Spread-spectrum frequency option available to reduce EMI in sensitive applications
What is LT8608IDC#TRMPBF used for?
The LT8608IDC#TRMPBF is designed for automotive point-of-load regulators, industrial 24 V DIN-rail instrument supplies, and telecom -48 V front-end converters that need to step down a wide-input rail to 3.3 V, 5 V, or 12 V logic supplies. Its 42 V input tolerance protects against load-dump transients in vehicle systems without additional clamping diodes. The device also suits industrial sensor transmitters and building-automation controllers powered from 24 V fieldbus rails requiring compact, efficient regulation.

Frequently Asked Questions
What input voltage range does LT8608IDC#TRMPBF support, and how does that benefit 24 V industrial rail designs?
The LT8608IDC#TRMPBF operates from 3 V to 42 V input, comfortably covering the 24 V nominal industrial supply rail as well as transient spikes up to 42 V caused by inductive switching or hot-plug events. This eliminates the need for external TVS clamping diodes in many PLC and sensor transmitter designs, reducing BOM cost and improving reliability.
How does the synchronous topology of LT8608IDC#TRMPBF improve efficiency compared to non-synchronous alternatives at medium load?
The integrated synchronous low-side MOSFET replaces a freewheeling Schottky diode, reducing conduction losses because a MOSFET's on-resistance (typically below 200 mΩ) dissipates far less power than a diode's 0.3 V to 0.5 V forward drop at 1 A. This efficiency gain is most significant at medium loads of 200 mA to 1 A, improving thermal performance in space-constrained DFN-8 enclosures.
When would an engineer select LT8608IDC#TRMPBF over a lower-voltage converter for an automotive 12 V application?
An engineer selects the LT8608IDC#TRMPBF over a 20 V-rated converter when the design must survive ISO 7637 automotive load-dump pulses that can spike the 12 V battery rail to 35 V to 40 V for tens of milliseconds. The 42 V absolute maximum rating of LT8608IDC#TRMPBF provides the necessary headroom, whereas lower-rated devices would require additional clamping circuits that add cost and PCB area.
