The HIP2105 and HIP2106A are high frequency MOSFET drivers optimized to drive two N-channel power MOSFETs in a synchronous buck converter topology. The HIP2105 has HI/LI inputs and the HIP2106A has a single PWM input. Both these drivers, combined with Renesas multi-phase buck PWM controllers, form a complete single-stage core-voltage regulator solution with high-efficiency performance at high switching frequency for advanced microprocessors.
Adaptive shoot-through protection (HIP2106A only) HI and LI inputs (HIP2105 only) 0.4Ω ON-resistance and 4A sink current capability Low tri-state hold-off time (20ns) (HIP2106A only) Supports 3.3V and 5V HI/LI or PWM input Power-On Reset (POR) Dual Flat No-Lead (DFN) package Near chip-scale package footprint, improves PCB efficiency and thinner in profile
