NS LM5115AMTX/NOPB

Контроллер вторичной стороны5 В ~ 30 В5 В ~ 7,5 В4 мА

Overview

The LM5115AMTX/NOPB controller contains all of the features necessary to produce multiple tracking outputs using 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. LM5115AMTX/NOPB can be also used as a standalone DC/DC synchronous buck controller (Refer tosection). 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 LM5115AMTX/NOPB 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.
