LM25115 Secondary Side Post Regulator Controller  
Check for Samples: LM25115

FEATURES  
DESCRIPTION  
The LM25115 controller contains all of the features  
necessary to implement multiple output power  
converters utilizing the Secondary Side Post  
Regulation (SSPR) technique. The SSPR technique  
develops a highly efficient and well regulated auxiliary  
output from the secondary side switching waveform of  
an isolated power converter. Regulation of the  
auxiliary output voltage is achieved by leading edge  
pulse width modulation (PWM) of the main channel  
duty cycle. Leading edge modulation is compatible  
with either current mode or voltage mode control of  
the main output. The LM25115 drives external high  
side and low side NMOS power switches configured  
as a synchronous buck regulator. A current sense  
amplifier provides overload protection and operates  
over a wide common mode input range. Additional  
features include a low dropout (LDO) bias regulator,  
error amplifier, precision reference, adaptive dead  
time control of the gate signals and thermal  
shutdown.
