P-DSO-8
Fast rise and fall times for frequencies up to 2 MHz
Capable of sinking more than 4A peak currents for lowest switching losses
Charges High Side MOSFET gate drive voltage from 6 to 12V according to PVCC
setting; Low Side MOSFET at 12 V.
Adjustable High 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
Footprint compatible to TDA21101G and HIP6601B
Ideal for multi-phase Desktop CPU supplies on motherboards and VRM麓s
