Introduction
High-efficiency step-down switching regulator BD9673AEFJ with up to 1.5A output, featuring an integrated power MOSFET, primarily used as a secondary-side power supply. For example, it can step down from fixed supplies such as 12V or 24V to output voltages of 1.2V, 1.8V, 3.3V, or 5V. This IC achieves miniaturization of external inductors/capacitors through 300kHz switching operation, the internal Nch-FET switch withstands up to 45V, current-mode control enables high-speed load transient response, and a simple external phase compensation scheme allows compact power supply designs to be easily realized with a wide range of external component values.
Features
- Built-in 200mΩ Nch MOSFET
- Output current 1.5A
- Oscillation frequency 300kHz
- Synchronizable with external clock (200kHz ~ 500kHz)
- Feedback voltage 1.0V ± 1.0%
- Built-in soft-start function
- Built-in overcurrent protection, UVLO, and thermal protection circuits
- ON/OFF control via EN pin (typical standby current 0A)
- Package: HTSOP-J8
Applications
- Universal home appliances with 12V/24V lines
