Integrated DC-DC converters
Enpirion announced the availability of the EN2300 family of fully integrated 12 Volt DC-DC converters, which are implemented with MOSFET technology to double the power density. The addition of the EN2340QI 4 Amp, EN2360QI 6 Amp, EN2390QI 9 Amp, and EN23F0QI 15 Amp devices capitalize on Enpirion’s field PowerSoC (power-system-on-chip) technology, which integrates the controller, power MOSFETs, high frequency input capacitors, compensation network and inductor.
Enpirion’s proprietary high-speed transistor structure implemented in 0.18u LDMOS process achieves a strong Figure of Merit (FOM = Gate Charge x On-state Resistance in units of milli-ohm nano-coulombs) to operate at high frequency while reducing switching losses.
The EN2300 devices offer compact solution footprints from 4 Amp at 190mm2 to 15 Amp at 308mm2 which represents up to a sixty percent area reduction versus competing alternatives at comparable performance. The devices support an input voltage range of 4.5 to 14V and an output voltage range of 0.6 to 5V.
