Features
Description
Auxiliary SMPS is particularly affected since it is
the entry point for all the biasing of control ICs and
cooling system powering. Standardization
towards "universal input" is reflected in more
stressful conditions for the power transistor used
as the main switch both in terms of blocking
voltage or current capability. Since almost all
auxiliary power supplies are based on fly-back
converters, the need for a blocking voltage as high
as 1500V and over, coupled with high switching
frequency operations, make the ESBTs the
perfect choice for such power supplies. The
STC08DE150HV, in conjunction with the PWM
L5991, perfectly fulfills the requirements and
brings high efficiency to the system

... Thanks to the adoption of the PWM L5991, the converter is able to operate in mixed mode. For higher power levels with a switching frequency close to 90kHz, the converter operates in Continuous Current Mode (CCM), while in stand-by and for power levels lower than 25W, the converter works in Discontinuous Current Mode (DCM switching frequency of about 35kHz. 2/5 STEVAL-ISA007V1 ...
