DC2744A

Demonstration circuit DC2744 is a two stage DC/DC boost converter featuring the LTC®7840 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 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.

• Minimum input voltage of 9V at IOUT = 0A to 0.7A
• Maximum input voltage of 36V at IOUT = 0A to 1.2A
• 240V ±3% VOUT at VIN = 9V to 36V, IOUT = 0A to 0.7A
• 500mVP-P typical output ripple VOUT at VIN = 9V to 36V, IOUT = 0.7A
• 150KHz nominal switching frequency
• 92% typical efficiency
