MIL-COTS Maxi, Mini, Micro
DC-DC Converters

MAXI-MINI-MICRO.jpg

Description

The Maxi, Mini, Micro family of DC-DC converters provides high density, low noise, with advanced power processing. The Maxi, Mini, and Micro converters are compact and efficient, and offer wide input ranges, remote sense, enhanced output programmability, and low standby dissipation. Low noise zero-current and zero-voltage switching and advanced power semiconductor packaging provide up to 120 W/in3 with low temperature gradients. 

Fully encapsulated, Maxi, Mini and Micro series DC-DC converters utilize a proprietary spin fill process that assures complete, void free encapsulation making them suitable for the harshest environments. Two grades
(H & M), are available with temperatures to -55°C operating and -65°C storage. H & M-Grade modules are qualified to the stringent environmental tests of
MIL-STD-810 and MIL-STD-202 and undergo 100% Environment Stress Screening.

Maxi, Mini, Micro: Basic power train and control (*Not included in Micro family)
The Maxi, Mini, Micro’s ZCS / ZVS power-processing architecture (Figure 1–3) enables efficient, low-noise, high-frequency operation. The main switch is common drain for improved thermal and noise management, the reset switch located within the primary control IC is common source for ease of control.

The control circuitry is integrated into two (primary and secondary side) ICs. The result is a significant reduction in parts with the ensuing savings in cost and increase in reliability. This integration also provides extra room for the power train.
Maxi, Mini, Micro transformers place the primary and secondary windings far apart, but contain the magnetic flux using a copper armor plated onto the ferrite core. The armor also conducts excess heat to the baseplate.
