HA16108P-E

Voltage Regulators - DC DC Switching Regulators Overview

The HA16108P-E is a primary control switching regulator IC designed for high-performance voltage mode control. It operates with an input voltage range of 12 V to 30 V and supports switching frequencies up to 600 kHz. The device features a built-in pre-driver circuit for power MOSFETs, under-voltage lockout (UVL) for both Vin and Vref, and an ON/OFF timer function for intermittent operation to prevent secondary overcurrent. It includes soft start, quick shutdown, and output protection functions.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix '-E' against official Renesas documentation to confirm specific environmental or packaging variants. Ensure compatibility with external components such as the timing capacitor for the ON/OFF function. Check for updated PCNs regarding label or assembly changes before finalizing procurement specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing primary-side controlled flyback converters requiring high switching frequencies. The integrated UVL and ON/OFF timer simplify design by reducing external component count. Ensure the application requires voltage mode control and can accommodate the specified input voltage range of 12 V to 30 V.

Voltage Regulators - DC DC Switching Regulators Part Context

The HA16108P belongs to Renesas' series of primary control switching regulator ICs. It is part of a family that includes similar devices like the HA16107P, which differs primarily in its over-current protection mechanism. These ICs are widely used in offline switch-mode power supply designs.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The HA16107P is a related part within the same series but utilizes timer-latch over-current protection instead of the ON/OFF timer found in the HA16108P. Verify if the specific protection logic aligns with the system requirements before substitution.
