PWM Controller suits DC/DC converters, power supplies.
October 9, 2009 -
MAGMA, available in ceramic DIL28 package, targets DC-DC converters and switching mode power supplies, where it brings maximum efficiency above 90% throughout -55 to +225°C range. Operating from 6-30 V input, it delivers PWM signal at constant frequency and duty cycles up to 90%. Chip can be forced to stand-by mode, with typ power consumption under 150 µA at 225°C. Threshold for power good signal can be adjusted, and sync pin can be driven by external clock.

CISSOID Introduces MAGMA, a High Temperature PWM Controller for DC-DC Converters and SMPS
Mont-Saint-Guibert, Belgium - October, 2009 - CISSOID, a leader in high temperature semiconductor solutions, has unveiled MAGMA, a PWM controller that operates reliably over the full temperature range [-55°C to +225°C]. MAGMA targets DC-DC converters and Switching Mode Power Supplies, where it brings maximum efficiency above 90% throughout the whole temperature range.
MAGMA can operate with input voltages from 6 to 30V and delivers a PWM signal at constant frequency and duty cycles up to 90%. The chip can be forced to a stand-by mode, with a typical consumption under 150µA at 225°C. The threshold for the "Power Good" signal can be adjusted. A Sync pin can be driven by an external clock for synchronization purposes while the internal clock is available on a Ckout pin. MAGMA also features an internal reference, input voltage feed forward, and a soft start activated whenever MAGMA comes out of stand-by or the output is enabled.
With MAGMA and their recently announced HYPERION driver, CISSOID provides the heart of high performance DC-DC converters reliable in the full temperature range [-55°C to +225°C], as expected by designers of aeronautics, oil & gas, train and automotive applications. Associated with Silicon Carbide power transistors or high reliability IGBTs, MAGMA and HYPERION enable smaller and more reliable battery chargers and bootstrap converters, with reduced cooling and better overall cost efficiency.
CHT-MAGMA is available immediately for sampling and evaluation in Ceramic DIL28 package. Pricing starts at $312.70 up to 200 units. For more information, visit www.cissoid.com or contact the company's representatives at www.cissoid.com/company/about-us/contacts.html.
