一,产品概述(General Description)   BoX嘉泰姆

---

          The CXSD6277/A/B series are designed to provide a low cost synchronousBoX嘉泰姆
Buck regulator for on-board DC to DC con-verter applications. The CXSD6277/A/BBoX嘉泰姆
series together with dual N-channel MOSFETs , provide aBoX嘉泰姆
low cost solution for such applications. Each device fea-tures an internalBoX嘉泰姆
200/400kHz oscillator, Power-On-Reset (POR) for both VCC and VC supplies,BoX嘉泰姆
an external pro-grammable soft-start function as well as output under-BoX嘉泰姆
voltage detection that latches off the device when an out-put short is detected.BoX嘉泰姆

五,产品封装图 (Package)BoX嘉泰姆
BoX嘉泰姆
FB (Pin 1)BoX嘉泰姆
Connect this pin to the output (VOUT) of the PWM con-verter via an external resistor divider to provide a voltageBoX嘉泰姆
feedback path for the converter. The output voltage set by the resistor divider is determined using the following BoX嘉泰姆

for-where ROUT is the resistor connected from VOUT to FB, and RGND is the resistor connected from FB to BoX嘉泰姆

ground.The voltage at this pin is also monitored for Under-Volt-age protection.BoX嘉泰姆
VCC (Pin 2)BoX嘉泰姆
Connect this pin to input voltage from 5V to 20V. This pin provides the bias for the control circuitry and the BoX嘉泰姆

power MOSFET driver (LDRV). The voltage at this pin is monitored for Power-On-Reset (POR) purpose.BoX嘉泰姆
LDRV (Pin 3)BoX嘉泰姆
Connect this pin to the gate of the low-side power MOSFET. This pin provides the gate drive for the MOSFET.BoX嘉泰姆
GND (Pin 4)BoX嘉泰姆
Signal and power ground for the IC. All voltage levels are measured with respect to this pin.BoX嘉泰姆
HDRV (Pin 5)BoX嘉泰姆
Connect this pin to the gate of the high-side power MOSFET. This pin provides the gate drive for the MOSFET.BoX嘉泰姆
VC (Pin 6)BoX嘉泰姆
This pin provides bias voltage to the high-side MOSFET driver. A bootstrap circuit may be used to pump a bootBoX嘉泰姆
voltage for enforcing the driving capability of the gate driver and improving the performance of the MOSFET.BoX嘉泰姆
COMP (Pin 7)BoX嘉泰姆
This pin is the output of the error amplifier. Add an exter-nal resistor-capacitor network to provide a loop compen-BoX嘉泰姆
sation for the PWM converter.BoX嘉泰姆

SS (Pin 8)BoX嘉泰姆
Connect a capacitor from this pin to ground.This capacitor,along with an internal 20μA current source, sets the soft-BoX嘉泰姆
start interval of the PWM converter and prevents the out-puts from overshoot as well as limits the input current.BoX嘉泰姆

Pull this pin below 0.5V can shutdown the converter.BoX嘉泰姆
