Overview
The BM2P104Q-Z is a non-isolated AC/DC converter IC from ROHM Semiconductor, designed for flyback topology applications. It integrates a switching MOSFET with a 650V breakdown voltage and a built-in high-voltage startup circuit. The device operates on PWM current mode control with a fixed switching frequency of 100 kHz. Key electrical parameters include a maximum duty cycle of 84%, a quiescent operating current of 1.2 mA, and an input supply voltage range from 8 V to 10.81 V. It supports a wide operating temperature range from -40°C to +105°C and is housed in a DIP-7 package.
Feature Summary
- Integrates a 650V super junction MOSFET and a high-voltage startup circuit to simplify design and reduce power consumption.
- Employs PWM current mode control with per-cycle current limiting to ensure excellent bandwidth and transient response.
- Includes frequency hopping functionality to assist in reducing electromagnetic interference (EMI).
- Features burst operation at light loads and soft start capability for improved efficiency and system protection.
Applications
- Power supplies for consumer electronics with AC plugs
- Non-isolated DC/DC conversion systems
- General purpose low-power adapter designs
Procurement Notes
Verify the specific suffix 'Q' against the manufacturer's latest datasheet to confirm packaging details and compliance status. Ensure the application circuit matches the non-isolated flyback requirements specified for this component. Confirm that the input voltage range aligns with the 8 V to 10.81 V specification for proper operation.
Selection Notes
Select this component for non-isolated applications requiring integrated switching capabilities. The 100 kHz frequency and 84% duty cycle suit moderate power levels. Consider the DIP-7 package for through-hole assembly needs. Evaluate thermal performance within the -40°C to +105°C range for the target environment.
Part Context
This part belongs to the BM2P series of AC/DC converters optimized for devices with power plugs. It combines controller and power switch functions into a single DIP-7 package. The series targets cost-sensitive, high-efficiency designs for household appliances and small electronic devices requiring non-isolated power conversion.
Replacement Considerations
Check for BM2P104 variants with different suffixes for packaging changes. Verify functional compatibility with BM2P134Q-Z or BM2P0391-Z only if voltage and frequency specifications align with the design requirements.
