Fast Transient Response Technology

H3R TM C t l E bl Q i k R t L d hH3RegTM Control Enables Quick Response to Load changes

Current mode control is a popular control method for switching regulators, but there are cases where the specifications for transient response characteristics with respect to load current changes

are insufficient. In these instances switching regulators utilizing hysteresis control are often used. Constant-on-time control, which is a type of hysteresis control, maintains constant output

voltage by feeding back ripple voltage that occurs within the output voltage and performing switching control while comparing the reference voltage with the bottom of the ripple voltage.

When the feedback voltage drops below the reference voltage a one-shot pulse is generated and the high-side switch turns on, supplying current to the output (from the input). In this method

sequential switching control is performed by simple comparison, virtually eliminating delay time for feedback control, enabling faster transient response than current mode control.

H3RegTM control is a more advanced type of constant on time control developed by ROHM. When the load current suddenly increases the output voltage drops and if the feedback voltage does

not rise higher than the reference voltage (even after the predetermined on-time) the on-time of the high-side switch is extended and more power is supplied, accelerating the return of the

output voltage. As a result, faster transient response can be obtained vs. constant on-time control. Plus, the number of switching operations during sudden load changes is decreased,

minimizing noise generation.

PWM and voltage-mode control circuits are built in, along with 2 external 10V Nch FET drive circuits. In addition, functions for adjusting the oscillation frequency and soft start time, providing overcurrent protection, and enabling synchronization with external clocks are included, providing greater design flexibility. Furthermore, an under-voltage lock out circuit (EXUVLO) with a high accuracy reference voltage for the CTL pin is connected, adjustable between VCC and GND (via resistance ratio). The controller also offers pre-bias compatibility and minimizes inrush current from the output side during startup.

Isolated DC/DC Power SupplyIsolated DC/DC Power Supply

pThe newly developed BD7F100HFN-LB isolated flyback DC/DC converter IC stabilizes the secondary output via primary flyback voltage control, eliminating the need for a feedback path from the output. As a result, the optocoupler typically used for isolating the feedback path in conventional isolated converters is no longer required. This reduces both costs and component count considerably, improving reliability. And in terms of performance, fast load response is achieved by utilizing adaptive on-time control, while an automatic light load mode ensures high efficiency across all load regions. Cross-regulation is also greatly improved. Ideal for isolated power supplies in a variety of equipment, including isolated gate driver power supplies for inverters
