The Gaia Converter transient suppressor LGDS-100 is an ultra-compact front-end power module designed to allow operation during voltage transients and spikes, occurring in avionics or military systems. The LGDS-100 delivers an output voltage adapted to Gaia Converter DC/DC modules. This module is optimized to provide high power efficiency up to 98%.
Gaia's LGDS-100 High-Reliability Transient suppressor is designed for higher operating temperatures of -40 to +105°C (optional -55°C) for typical military & airborne applications:
Available Options (see specs for details):
• T = -55°C Start-Up Temperature
• S = Screening & Serialization
Modes of Operation
The LGDS-100 features 3 modes of operations as follows:
Normal operation: Normal operation occurs when the input voltage is within the permanent range (9-42V) . The LGDS-100 is then operating in steady transparency state.
Transient operation: The LGDS-100 clamps input transient up to 202V/350ms, or 101V/400ms, and keeps it's output at 42V or less. The LGDS-100 series is compliant with the inter-national input bus standards
DEF-STAN-61-5 Part 6 Issue 6,
Power fail operation: When a failure occurs such as an under-voltage, an over current or an over temperature, the LGDS-100 turns to power fail mode and stops operation until the failure is removed. The LGDS-300 features 3 protection functions : input under-voltage lockout (UVLO), output over current protection (OCP) and over temperature protection (OTP).
