七,功能概述1wx嘉泰姆


Internal Regulator1wx嘉泰姆
    The CXSD61055 is a current mode step down DC/DC converter that provides excellent transient1wx嘉泰姆
response with no extra external compensation components. This device contains an internal,1wx嘉泰姆
low resistance, high voltage power MOSFET, and operates at a high 600K operating frequency to1wx嘉泰姆
ensure a compact, high efficiency design with excellent AC and DC performance. 1wx嘉泰姆
Error Amplifier1wx嘉泰姆
The error amplifier compares the FB pin voltage with the internal FB reference (V FB) and outputs a1wx嘉泰姆
current proportional to the difference between the two. This output current is then used to charge1wx嘉泰姆
or discharge the internal compensation network to form the COMP voltage, which is used to1wx嘉泰姆
control the power MOSFET current.The optimized internal compensation network minimizes the1wx嘉泰姆
external component counts and simplifies the control loop design. 1wx嘉泰姆
Internal Soft-Start1wx嘉泰姆
The soft-start is implemented to prevent the converter output voltage from overshooting1wx嘉泰姆
during startup. When the chip starts, the internal circuitry generates a soft-start voltage (SS)1wx嘉泰姆
ramping up from 0V to 0.6V. When it is lower than the internal reference (REF), SS overrides1wx嘉泰姆
REF so the error amplifier uses SS as the reference. When SS is higher than REF, REF1wx嘉泰姆
regains control. The SS time is internally fixed to 1 ms. Over-Current-Protection and Hiccup1wx嘉泰姆
The CXSD61055 has cycle-by-cycle over current limit when the inductor current peak value1wx嘉泰姆
exceeds the set current limit threshold. Meanwhile, output voltage starts to drop until FB1wx嘉泰姆
is below the Under-Voltage (UV) threshold,typically 30% below the reference. Once a UV is1wx嘉泰姆
triggered, the CXSD61055 enters hiccup mode to periodically restart the part. This protection mode1wx嘉泰姆
is especially useful when the output is dead-short to ground. The average short circuit1wx嘉泰姆
current is greatly reduced to alleviate the thermal issue and to protect the regulator. The CXSD610551wx嘉泰姆
exits the hiccup mode once the over current condition is removed. 1wx嘉泰姆
Startup and Shutdown1wx嘉泰姆
If both VIN and EN are higher than their appropriate thresholds, the chip starts. The1wx嘉泰姆
reference block starts first, generating stable reference voltage and currents, and then the1wx嘉泰姆
internal regulator is enabled. The regulator provides stable supply for the remaining1wx嘉泰姆
circuitries. Three events can shut down the chip: EN low, VIN low and thermal shutdown. In the1wx嘉泰姆
shutdown procedure, the signaling path is first blocked to avoid any fault triggering. The COMP1wx嘉泰姆
voltage and the internal supply rail are then pulled down. The floating driver is not subject to1wx嘉泰姆
this shutdown command.1wx嘉泰姆
