产品概述 返回TOP
The CXSU63236 boost converter incorporate high-performance, current-mode, and frequency selectable pulse width modulation (PWM) circuitry with a built-in N-channel MOSFET to provide a highly efficient regulator. The CXSU63236’s frequency can be selected by user to operate at either 600kHz or 1.2MHz. High switching frequency allows easily filtering and faster loop performance. An external compensation pin provides the user flexibility in determining loop dynamics, allowing the use of small, low ESR ceramic output capacitors. The current-mode architecture provides fast transient response to pulsed loads. The internal N-channel MOSFET can produce output voltage as high as 28V. User programmed soft-start with an external capacitor determines the input current ramp rate. The CXSU63236 is available in a 10-pin TDFN3X3 package
