P-DSO-8-7
P-DSO-14-3
Fast rise and fall times for frequencies up to 2 MHz
Capable of sinking more than 4 A peak current for lowest switching losses
Charges the High Side and Low Side MOSFET麓s gate to 6..12 V according to
PVCC setting.
Adjustable High Side and Low Side MOSFET gate drive voltage via PVCC pin for
optimizing ON losses and gate drive losses
Integrates the bootstrap diode for reducing the part count
Prevents from cross-conducting by adaptive gate drive control
High voltage rating on Phase node
Supports shut-down mode for very low quiescent current through three-state input
Compatible to standard PWM controller ICs (Intersil, Analog Devices)
Floating High Side MOSFET drive
鈥?/div>
Ideal for multi-phase Desktop CPU supplies on motherboards and VRM麓s
