JW5513
The JW5513 is a synchronous high-efficiency, step-up boost converter. The device adopts constant-off-time (COT) control topology. The integrated low RDS(ON) switches minimize the conduction loss.
The JW5513 supports the selection of pulse-skip mode (PFM), forced continuous conduction mode (PWM), and ultrasonic mode(USM) in light-load condition. The device features cycle by cycle peak current limit up to 15A. The low output voltage ripple, the small external inductor and the capacitor size are achieved at programmable pseudo-constant frequency.
JW5513 guarantees robustness with over voltage protection and over temperature protection
