Delphi Series E48SB, 240W Eighth BrickwwwB.DatuaShseet4CU.coom nverter
DC/DC Power Modules: 48Vin, 9.6V/25A out
Delta Electronics, Inc., a world leader in power systems technology and
manufacturing, has introduced the E48SB, eighth brick sized 240W
bus converter, into their Delphi Series of board mounted DC/DC power
converters to support the intermediate bus architecture to power multiple
downstream non-isolated point-of-load (POL) converters. The E48SB
product family features an input voltage of 38V to 55V, and provides up to
240W (9.6V and above) of power in an industry standard eighth brick
footprint. Typical efficiency of 9.6V module is 96.5%. With optimized
component placement, creative design topology, and numerous patented
technologies, the E48SB bus converters deliver outstanding electrical and
thermal performance. An optional heatsink is available for harsh thermal
requirements.

Figure 8: Output voltage response to step-change in load
current (50%-75%-50% of Io, max; di/dt = 0.1A/µs). Load cap:
10µF, tantalum capacitor and 1µF ceramic capacitor. Top Trace:
Vout (100mV/div, 100us/div), Bottom Trace: Iout (10A/div).
Scope measurement should be made using a BNC cable
(length shorter than 20 inches). Position the load between 51
mm to 76 mm (2 inches to 3 inches) from the module.
Figure 9: Output voltage response to step-change in load
current (50%-75%-50% of Io,max; di/dt=1A/µs). Load cap:
10uF ,tantalum capacitor and 1µF ceramic capacitor. Top Trace:
Vout (200mV/div, 100us/div), Bottom Trace: Iout (5A/div).
Scope measurement should be made using a BNC cable
(length shorter than 20 inches). Position the load between 51
mm to 76 mm (2 inches to 3 inches) from the module.
