The LT3437 is a high voltage monolithic buck switching regulator designed for various power conversion needs, including 14V and 42V automotive systems, industrial power, distributed power, and battery-powered applications. It accepts a wide input voltage range from 3.3V to 60V and provides load dump protection up to 80V.
This regulator features a 500mA peak switch current and operates at a 200kHz switching frequency. It includes a saturating switch design with 0.8Ω on-resistance and maintains peak switch current over the full duty cycle range. The device utilizes Burst Mode operation for low quiescent current (100µA) at light loads and offers a low shutdown current of less than 1µA.
The LT3437 is available in a small, thermally enhanced 10-pin DFN package measuring 3mm x 3mm with a low profile of 0.75mm. This surface-mount package is suitable for space-constrained designs. The regulator also offers soft-start capability and can be easily synchronized.
Key electrical characteristics include a 1.25V feedback reference voltage. The design is optimized for high efficiency across a wide input voltage range.
The input voltage range is 3.3V to 60V, with transient protection up to 80V.
The maximum peak switch current is 500mA.
The switching frequency is 200kHz.
It comes in a 10-Pin DFN package measuring 3mm x 3mm with a 0.75mm height.
The quiescent current is 100µA typical in Burst Mode operation.
The shutdown current is less than 1µA.
