BM2P0161K-Z

Overview

The BM2P0161K-Z is a PWM type DC/DC converter IC with an integrated switching MOSFET, designed for AC/DC conversion in products with power outlets. It supports both isolated and non-isolated topologies. Key electrical parameters include a drain voltage rating of 800V, an input voltage range of 8.9V to 26V, and a maximum switching frequency of 65kHz. The device operates within a temperature range of -40°C to +105°C and is housed in a DIP-7 package.

Feature Summary

• Integrates an 800V耐压 start circuit and MOSFET to facilitate low-power design.
• Employs current mode control with per-cycle current limiting for superior bandwidth and transient response.
• Features frequency hopping and burst operation at light loads to enhance efficiency and reduce EMI.

Applications

• Power supply systems for consumer electronics with power outlets
• Low-power isolated AC/DC converters
• Non-isolated high-precision buck converters

Procurement Notes

Verify the specific suffix 'K' against the manufacturer's official documentation to confirm packaging details and compliance status. Ensure the selected variant matches the required isolation topology, as the base series supports both isolated and non-isolated designs. Cross-reference the DIP-7 package dimensions with your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component for applications requiring an integrated solution for AC/DC conversion without external gate drivers. The 800V rating suits higher voltage bus applications compared to lower-rated counterparts. Consider the fixed 65kHz switching frequency and light-load frequency reduction features when designing for strict EMI or efficiency targets.

Part Context

This part belongs to the BM2P series of PWM DC/DC converter ICs from ROHM Semiconductor. The series is optimized for AC/DC converters in devices with power sockets, offering integrated high-voltage MOSFETs and start circuits to simplify design and reduce component count.

Replacement Considerations

BM2P0161-Z is the base model; verify if the 'K' suffix denotes a specific packaging or tape-and-reel variation rather than a functional change.
