Switching Regulator
with Built-in Power MOSFET
BD9329AEFJ
No.11027EAT56
● Description
The BD9329AEFJ is a synchronous step-down switching regulator that integrates 2 low resistance N-channel MOSFETs.
It achieves 3A continuous output current over a wide input supply range. Current mode operation provides fast transient
response and easy phase compensation.
● Features
1) Wide operating INPUT Range 4.2V ～ 18.0V
2) 3A Output Current
3) Hi-side / Lo-side FET ON-resistance; 0.15 / 0.13 ? Power Switch
4) Low ESR Output Ceramic Capacitors are Available
5) Low Standby Current during Shutdown Mode
6) 380 kHz Fixed Operating Frequency
7) Feedback voltage 0.9V ±1.5% Accuracy at room temp. (±2.0% guaranteed for -25 ℃ to 85 ℃ temperature range)
8) Protection Circuits
Under Voltage Lockout Protection
Thermal Shutdown
Over Current Protection
9) HTSOP-J8 Package with Exposed thermal PAD.
● Applications
Distributed Power System
Pre-Regulator for Linear Regulator
● Absolute maximum ratings (Ta = 25 ℃ )
