MOSFET Gate Drivers (DH_, DL_)
The high-side drivers (DH1 and DH2) and low-side dri-
vers (DL1 and DL2) drive the gates of external n-channel
MOSFETs. The high-peak sink and source current capa-
bility of these drivers provides ample drive for the fast
rise and fall times of the switching MOSFETs. Faster rise
and fall times result in reduced switching losses. For low-
output, voltage-regulating applications where the duty
Figure 5. Defining the Voltage-Positioning Window
cycle is less than 50%, choose high-side MOSFETs (Q2
and Q4, Figure 6) with a moderate R DS(ON) and a very
low gate charge. Choose low-side MOSFETs (Q1 and
Q3, Figure 6) with very low R DS(ON) and moderate gate
charge. The driver block also includes a logic circuit that
provides an adaptive nonoverlap time (30ns typ) to pre-
vent shoot-through currents during transition. Figure 7
shows the dual-phase, single-output buck regulator.
