Overview
The BM1P065FJ-E2 is a PWM control IC for DC/DC converters manufactured by ROHM Semiconductor. It operates within an input voltage range of 8.9 V to 26 V and provides a single output capable of delivering up to 1 A at 12.5 V. The device features a fixed switching frequency of 65 kHz with a maximum duty cycle of 82%. Designed for surface mount installation, it utilizes an SOP-8 package and functions reliably across a temperature range from -40 °C to +85 °C.
Feature Summary
- Integrates a high-voltage start circuit to facilitate low-power system design without external startup components.
- Supports both insulated and non-insulated converter topologies for flexible power supply architectures.
- Employs current mode control with per-cycle current limiting to ensure stable bandwidth and transient response.
Applications
- Low-power AC/DC converters for consumer electronics
- Adapters for devices with standard power interfaces
- Insulated and non-insulated DC/DC conversion stages
Procurement Notes
Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm pinout compatibility and electrical specifications. Ensure the SOP-8 package dimensions align with your PCB footprint requirements. Confirm RoHS compliance status directly with the supplier documentation prior to integration into production assemblies.
Selection Notes
Select this component when designing systems requiring a fixed 65 kHz switching frequency and integrated high-voltage startup capabilities. It is suitable for applications needing a single regulated output within the specified voltage range. Consider its thermal performance in the SOP-8 package if operating near the upper limits of the specified temperature range.
Part Context
This part belongs to ROHM's series of PWM control ICs designed for efficient power management. It is engineered to simplify the design of various DC/DC converters by integrating essential protection features and control logic. The device supports external MOSFETs and current sensing resistors to allow for customized power stage configurations.
Replacement Considerations
Consult official substitution lists for verified alternatives. Generic replacements may differ in start circuit integration or switching frequency characteristics.
