一,产品概述(General Description) m8r嘉泰姆

The CXSD62114 integrates dual step-down, constant-on-time,m8r嘉泰姆

synchronous PWM controllers (that drives dual N-channel MOSFETs for
each channel) and two low drop-out regulators as well as various protections
into a chip.The PWM controllers step down high voltage of a battery
to generate low-voltage for NB applications. The output of PWM1 and
PWM2 can be adjusted from 2V to 5.5V by setting a resistive voltage-divider
from VOUTx to GND.The linear regulators provide 5V and 3.3V output for
standby power supply. The linear regulators provide up to 100mA output
current. When the PWMx output voltage is higher than LDOx bypass threshold, the related LDOx regulator is shut off and its output is connected to VOUTx
by internal switchover MOSFET. It can save power dissipation. The charge
pump circuit with 250kHz clock driver uses VOUT1 as its power supply to generate ap-proximately 15V DC voltage.
The CXSD62114 provides excellent transient response and accurate DC output voltage in either PFM or PWM Mode. In Pulse-Frequency Mode (PFM),
the CXSD62114 provides very high efficiency over light to heavy loadsm8r嘉泰姆

with loading-modulated switching frequencies. The Forced-PWM Mode works nearly at constant frequency for low-noise requirements. The unique ultrasonic
mode maintains the switching frequency above 25kHz, which eliminates noise in audio application.The CXSD62114A/D has individual enable controls for
each PWM channels. Pulling both EN1/2 pin low shuts down the all of outputs unless LDO3 output. The LDO3 and LDO5 of CXSD62114B/C are always on standby power.The CXSD62114 is available in a TQFN3x3-20 package.

the node.
Decoupling capacitor, the resistor dividers, boot capacitors, and current-limit stetting resistor should
be close to their pins. (For example, place the decoupling ceramic capacitor near the drain of the
high-side MOSFET as close as possible. The bulk capacitors are also placednear the drain).
The input capacitor should be near the drain of the upper MOSFET; the high quality ceramic decoupling
capacitor can be put close to the VCC and GND pins;the output capacitor should be near the loads. The
input capacitor GND should be close to the output ca-pacitor GND and the lower MOSFET GND.
The drain of the MOSFETs (V IN and PHASEx nodes)should be a large plane for heat sinking. And PHASEx
pin traces are also the return path for UGATEx. Con-nect these pins to the respective converter’s upper
MOSFET source.
The controller used ripple mode control. Build the re-sistor divider close to the FB1 pin so that the high
impedance trace is shorter when the output voltage is in ad justable mode. And the FB1 pin traces can’t be
close to the switching signal traces (UGATEx, LGATEx,BOOTx, and PHASEx).
The PGND trace should be a separate trace, and in-dependently go to the source of the low-side MOSFETs
for current-limit accuracy.
