一,产品概述(General Description)         D3h嘉泰姆
        The CXSD62116A/B/C is a voltage mode, fixed 300kHz-switching frequency,D3h嘉泰姆
and synchronous buck controller. The CXSD62116A/B/C allows wide input voltageD3h嘉泰姆
that is either a single 5~12V or two supply voltage(s) for various applications.D3h嘉泰姆
A power-on-reset (POR) circuit monitors the VCC supply voltage to preventD3h嘉泰姆
wrong logic controls. A built-in digital soft-start circuit prevents the outputD3h嘉泰姆
voltages from overshoot as well as limits the input current. An internalD3h嘉泰姆
0.6V temperature-compensated reference voltage with high accuracy isD3h嘉泰姆
designed to meet the requirement of low output voltage applications.D3h嘉泰姆
The CXSD62116A/B/C provides excellent output voltage regulations againstD3h嘉泰姆
load current variation.D3h嘉泰姆
     The controller’s over-current protection monitors the output currentD3h嘉泰姆
by using the voltage drops across the RDS(ON)of low-side MOSFET,D3h嘉泰姆
eliminating the need for a current sensing resistor that features highD3h嘉泰姆
efficiency and low cost.D3h嘉泰姆
     The CXSD62116A/B/C also integrates over-voltage protection (OVP) andD3h嘉泰姆
under-voltage protection circuit which moni-tors the FB voltage to preventD3h嘉泰姆
the PWM output from over and under voltage.D3h嘉泰姆
     The CXSD62116A/B/C is available in a simple SOP-8P package.D3h嘉泰姆

Layout ConsiderationD3h嘉泰姆
In any high switching frequency converter, a correct lay-out is important to ensure proper operation of theD3h嘉泰姆
regulator. With power devices switching at 300kHz,the resulting current transient will cause voltage spike acrossD3h嘉泰姆
the interconnecting impedance and parasitic circuit elements. As an example, consider the turn-off transitionD3h嘉泰姆
of the PWM MOSFET. Before turn-off, the MOSFET is car rying the full load current. During turn-off, current stopsD3h嘉泰姆
flowing in the MOSFET and is free-wheeling by the lower MOSFET and parasitic diode. Any parasitic inductance ofD3h嘉泰姆
the circuit generates a large voltage spike during the switching interval. In general, using short and wide printedD3h嘉泰姆
circuit traces should minimize interconnecting imped-D3h嘉泰姆

ances and the magnitude of voltage spike. And signal and power grounds are to be kept separate till combinedD3h嘉泰姆

using ground plane construction or single point grounding. Figure 8. illustrates the layout, with bold linesD3h嘉泰姆
indicating high current paths; these traces must be short and wide. Components along the bold lines should beD3h嘉泰姆

placed lose together. Below is a checklist for your layout:D3h嘉泰姆

- Keep the switching nodes (UGATE, LGATE, and PHASE) away from sensitive small signal nodes since theseD3h嘉泰姆

nodes are fast moving signals. Therefore, keep traces to these nodes as short as possible.D3h嘉泰姆

- The traces from the gate drivers to the MOSFETs (UG and LG) should be short and wide.D3h嘉泰姆

- Place the source of the high-side MOSFET and the drain of the low-side MOSFET as close as possible. Minimiz-D3h嘉泰姆
ing the impedance with wide layout plane between the two pads reduces the voltage bounce of the node.D3h嘉泰姆
- Decoupling capacitor, compensation component, the resistor dividers, and boot capacitors should be closeD3h嘉泰姆
their pins. (For example, place the decoupling ceramic capacitor near the drain of the high-side MOSFET asD3h嘉泰姆
close as possible. The bulk capacitors are also placed near the drain).D3h嘉泰姆
- The input capacitor should be near the drain of the up-per MOSFET; the output capacitor should be near theD3h嘉泰姆
loads. The input capacitor GND should be close to the output capacitor GND and the lower MOSFET GND.D3h嘉泰姆
- The drain of the MOSFETs (VIN and PHASE nodes) should be a large plane for heat sinking.D3h嘉泰姆
- The ROCSET resistance should be placed near the IC as close as possible.Close to ICD3h嘉泰姆
