一,产品概述(General Description)   x5u嘉泰姆

---

          The CXSD6277/A/B series are designed to provide a low cost synchronousx5u嘉泰姆
Buck regulator for on-board DC to DC con-verter applications. The CXSD6277/A/Bx5u嘉泰姆
series together with dual N-channel MOSFETs , provide ax5u嘉泰姆
low cost solution for such applications. Each device fea-tures an internalx5u嘉泰姆
200/400kHz oscillator, Power-On-Reset (POR) for both VCC and VC supplies,x5u嘉泰姆
an external pro-grammable soft-start function as well as output under-x5u嘉泰姆
voltage detection that latches off the device when an out-put short is detected.x5u嘉泰姆

五,产品封装图 (Package)x5u嘉泰姆
x5u嘉泰姆
FB (Pin 1)x5u嘉泰姆
Connect this pin to the output (VOUT) of the PWM con-verter via an external resistor divider to provide a voltagex5u嘉泰姆
feedback path for the converter. The output voltage set by the resistor divider is determined using the following x5u嘉泰姆

for-where ROUT is the resistor connected from VOUT to FB, and RGND is the resistor connected from FB to x5u嘉泰姆

ground.The voltage at this pin is also monitored for Under-Volt-age protection.x5u嘉泰姆
VCC (Pin 2)x5u嘉泰姆
Connect this pin to input voltage from 5V to 20V. This pin provides the bias for the control circuitry and the x5u嘉泰姆

power MOSFET driver (LDRV). The voltage at this pin is monitored for Power-On-Reset (POR) purpose.x5u嘉泰姆
LDRV (Pin 3)x5u嘉泰姆
Connect this pin to the gate of the low-side power MOSFET. This pin provides the gate drive for the MOSFET.x5u嘉泰姆
GND (Pin 4)x5u嘉泰姆
Signal and power ground for the IC. All voltage levels are measured with respect to this pin.x5u嘉泰姆
HDRV (Pin 5)x5u嘉泰姆
Connect this pin to the gate of the high-side power MOSFET. This pin provides the gate drive for the MOSFET.x5u嘉泰姆
VC (Pin 6)x5u嘉泰姆
This pin provides bias voltage to the high-side MOSFET driver. A bootstrap circuit may be used to pump a bootx5u嘉泰姆
voltage for enforcing the driving capability of the gate driver and improving the performance of the MOSFET.x5u嘉泰姆
COMP (Pin 7)x5u嘉泰姆
This pin is the output of the error amplifier. Add an exter-nal resistor-capacitor network to provide a loop compen-x5u嘉泰姆
sation for the PWM converter.x5u嘉泰姆

SS (Pin 8)x5u嘉泰姆
Connect a capacitor from this pin to ground.This capacitor,along with an internal 20μA current source, sets the soft-x5u嘉泰姆
start interval of the PWM converter and prevents the out-puts from overshoot as well as limits the input current.x5u嘉泰姆

Pull this pin below 0.5V can shutdown the converter.x5u嘉泰姆
