Product Details

Demonstration circuit DC2744 is a two stage DC/DC boost converter featuring the LTC7840, a constant frequency current mode boost controller. The DC2744A operates over a 9V to 36V input voltage range. The first stage boost generates VOUT1 at 48V. The second stage boost takes this 48V input and provides a 240V output with 0.7A of load current. The 150kHz constant frequency operation results in a small and efficient circuit. The converter provides high output voltage accuracy (typically ±3%) over a wide load range with no minimum load requirement. The demonstration circuit can be easily modified to generate different output voltages.

The DC2744 has small circuit footprint. It is a high performance cost effective solution for applications that require high step-up voltage ratios and high output power.
