NCP1052XP136

NCP1052XP136, manufactured by ON Semiconductor, is a highly efficient, low-cost photon controller integrated circuit (IC) designed to be used as a current-mode boost pulse width modulated (PWM) fixed operating frequency control system. It is ideal for multiple applications, including AC/DC power systems and offline switchers.

Application Field

The NCP1052XP136 is ideal for controlling multiple applications, including AC/DC power systems, offline switchers, and low power lighting systems. This integrated circuit offers a wide range of features, including high-efficiency boost PWM controller and overcurrent protection, while meeting the requirements of a wide range of applications. Additionally, the NCP1052XP136 offers synchronous rectification and soft-start features, as well as a wide output voltage range of 34V to 56V and a temperature range of -40C to +105C.

Working Principle

The NCP1052XP136 works in two phases: a startup phase and a steady-state phase. In the startup phase, the NCP1052XP136 uses a soft-start feature to gradually ramp up the output voltage to its programmed value. This allows the system to start without any transient current flowing in the output. In the steady-state phase, the NCP1052XP136 uses a current-mode PWM control system for controlling the output voltage. The PWM control system uses a high-side/low-side driver that controls the power MOSFETs – both having dedicated control pins used to set the peak current limit. This enables the drive circuit to detect the current flowing through the inductor, thus allowing the controller to regulate the output voltage accurately.

The NCP1052XP136 also has extensive safety features, including multiple protection mechanisms to ensure that the system remains safe in a wide range of conditions. These features include output over-voltage protection, over-current protection, short circuit protection, and thermal shutdown. Additionally, the NCP1052XP136 has a user-selectable blanking time feature to prolong the life of the power MOSFETs.
