The E48SX, 48V input, single output, isolated DC/DC converter, delivers up to 40A of output current or 75W in a true eighth brick footprint (0.75" width, exactly half the size of a quarter brick) and industry standard eighth brick pinout. With optimized component placement, creative design topology and patented technologies from Delta's World Wide Engineering Teams, the Delphi Series E48SX converter delivers not only outstanding electrical and thermal performance, but has industry leading efficiencies which translate into more board space at less cost for our customer's space constrained and cost-sensitive applications.

The E48SX converter operates from a wide input voltage range of 36V to 75V and is available in output voltages of 1.2V to 5V. The E48SX units have a typical ripple & noise parameter of only 16mV peak-to-peak for 1.2V output at full load (40A) and only 20mVp-p for 1.5V and 1.8V outputs at full load (30A) when tested with only a 1uF ceramic output capacitor, making their performance among the best in the industry. In addition to utilizing several key patents for high density packaging, the E48SX converter employs yet another patent pending technology, which simply put, allows the output trim pin to intelligently function as a secondary side synchronization (±10%), which further reduces the output ripple and noise. This offers a significant advantage to those applications that are extremely noise sensitive. By employing the latest patented technology, wherein the magnetic feedback is fed through an orthogonal magnetic field in the power magnetic, The Delphi Series E48SX unit offers the fastest transient response in the Industry. When tested with no external output capacitors (compared to others tested with a 10uF tantalum plus a 1uF ceramic), typical response is less than 60mVp-p/30uS for 100% step load and 35mVp-p/30uS for 25% step load (1.5V and 1.8V outputs).

Delta's Delphi Series E48SX converter comes complete with a host of industry-standard features to insure that this unit will reliably perform in the harshest environments. All modules are fully protected against abnormal input/output voltage, current, and temperature conditions and meets basic insulation requirements of EN60950. The E48SX converters offer monotonic startup into normal or pre-biased loads and are available in both surface-mount or through-hole packages.

Sample quantities of Delta's Delphi Series E48SX converters are available. In OEM quantities of 1000 pieces, the unit price is US$42. Standard lead-time for this product is from stock to 8 weeks, depending on the volume.
