General Description
The HV9606 PWM controller allows the design of high efficiency (>90%) power supplies for distributed board mounted power (BMP) applications. Due to its high frequency capability it can provide high currents (20A @ 3.3V) with small transformers and due to its low internal operating voltage and current is also able to achieve high efficiencies in low power applications.
