CONSONANCE 4.
5V to 32V Input Current Mode Boost DC-DC Controller CN5120 General Description: The CN5120 is a current mode fixed-frequency PWM controller for both flyback and step-up DC-DC converters.
The device operates from an input supply between 4.
5V and 32V and provides to drive an external N-channel MOSFET.
The CN5120 contains all the necessary building blocks including a bandgap reference, a 330KHz oscillator, current-mode control circuitry, chip shutdown block, softstart block and gate driver, etc.
Current mode control provides improved transient response and simplified loop compensation.
On-chip soft start reduces the inrush current on power up.
The other features include chip shu...
