What are the key features of LT1374HVCR#PBF?
- 4.5 A peak switch current with 500 kHz PWM switching frequency enables compact inductor selection and high power density in step-down DC-DC converter designs
- Wide 5 V to 32 V input voltage range accommodates automotive, industrial, and telecom power bus voltages in a single-chip solution
- Current-mode control architecture provides inherent cycle-by-cycle current limiting and fast transient response for demanding point-of-load power regulation
What is LT1374HVCR#PBF used for?
The LT1374HVCR#PBF is used in industrial and automotive point-of-load DC-DC conversion applications where a wide input voltage range of 5 V to 32 V must be stepped down efficiently at up to 4.5 A. Its 500 kHz switching frequency and current-mode PWM control make it well-suited for distributed power systems in telecom equipment, motor controller boards, and embedded computing platforms requiring robust, compact power regulation.

Frequently Asked Questions
What input voltage range and output current capability does the LT1374HVCR#PBF support?
The LT1374HVCR#PBF accepts input voltages from 5 V to 32 V and can deliver up to 4.5 A peak switch current, making it suitable for high-current step-down regulation in automotive 12 V to 24 V systems and industrial 24 V power rails requiring efficient point-of-load conversion.
How does the 500 kHz switching frequency of the LT1374HVCR#PBF affect external component selection?
The 500 kHz switching frequency of the LT1374HVCR#PBF allows use of smaller inductors, typically in the 10 µH to 33 µH range, and lower-capacitance output filter capacitors compared to lower-frequency regulators, resulting in a more compact and lighter PCB design for power-dense industrial and computing applications.
What does current-mode control in the LT1374HVCR#PBF offer over voltage-mode control for power supply designs?
Current-mode control in the LT1374HVCR#PBF provides automatic cycle-by-cycle peak current limiting at 4.5 A, inherent feed-forward rejection of input voltage transients, and simpler loop compensation compared to voltage-mode controllers, improving transient response and short-circuit protection in demanding industrial and automotive power converter designs.
