Overview
The BM2P104H-Z is an AC/DC converter IC from ROHM Semiconductor, designed for PWM DC/DC conversion with integrated switching MOSFETs. It features a DIP-7 package and supports both isolated and non-isolated topologies. The device operates within a VCC voltage range of 10.9V to 30V and includes a built-in 650V starter circuit. Key electrical parameters include a maximum drain voltage (Vmax) of 730V, a switch frequency selectable at 65kHz, 100kHz, or 130kHz, and a maximum duty cycle of 82%. It functions reliably between -40°C and +105°C.
Feature Summary
- Integrates a 650V super junction MOSFET and a high-voltage startup circuit to facilitate low-power system design.
- Employs current mode control with per-cycle current limiting to ensure excellent bandwidth and transient response performance.
- Incorporates frequency hopping and burst operation modes at light loads to achieve high efficiency and reduced electromagnetic interference.
Applications
- Low-power AC/DC power supply systems
- Non-isolated converter designs
- Isolated converter designs
Procurement Notes
Verify the specific switch frequency configuration required for your application, as the BM2P104H-Z supports multiple frequencies including 65kHz, 100kHz, and 130kHz. Confirm that the 730V maximum drain voltage rating aligns with your circuit's peak voltage stresses. Ensure the DIP-7 package dimensions fit your PCB layout constraints. Check official datasheets for detailed thermal management requirements given the operating temperature range up to 105°C.
Selection Notes
Select the BM2P104H-Z when designing AC/DC converters requiring integrated high-voltage components and flexible switching frequency options. Its current mode control offers superior transient response compared to voltage mode alternatives. The inclusion of light-load burst operation makes it suitable for applications demanding high efficiency across varying load conditions. Consider its suitability for both isolated and non-isolated architectures depending on specific insulation requirements.
Part Context
The BM2P104H-Z belongs to ROHM's series of AC/DC PWM DC/DC converter ICs. This family targets various consumer and industrial products needing efficient power conversion. Unlike some variants restricted to non-isolated use, this model supports both isolated and non-isolated configurations, offering greater design flexibility for different power supply architectures.
