Cxle8607 is a high efficiency and high precision boost DC-DC control chip. Built in high precision error amplifier, fixed turn off time control circuit, PWM comparator, peak current current limiting circuit

Cxle8607 is a high efficiency and high precision boost DC-DC control chip. Built in high precision error amplifier, fixed turn off time control circuit, PWM comparator, peak current current limiting circuit, power tube drive circuit, etc
Suitable for wide voltage input boost applications. Cxle8607 adopts the control mode of fixed off time, and its working frequency can reach 1MHz at most, which can reduce the volume of external inductance and filter capacitance, improve efficiency and save PCB area. The minimum turn off time is 620ns, which can be adjusted by the external capacitance, and the working frequency can also be adjusted according to the user's requirements. Because of the current mode control, the system has fast transient response speed to the input bus voltage and load transient.
