Regulator for DDR-SDRAM Cores
BD9535MUV
No.10030EBT34
●Description BD9535MUV is a 2ch switching
regulator controller with high output current which can achieve low output voltage (0.7V~
2.0V) from a wide input voltage range (4.5V~25V). High efficiency for the switching
regulator can be realized by utilizing an external N-MOSFET power
transistor. A new technology called H3RegTM is a Rohm proprietary control method to realize ultra high transient response against load change. SLLMTM (Simple Light Load Mode) technology is also integrated to improve efficiency in light load mode, providing high efficiency over a wide load range. For the soft start/stop function, variable frequency function, short circuit protection function with timer latch, and tracking function are all built in. This 2ch switching
regulator is specially designed for Chipset and Front Side Bus.
●Features 1) 2ch H3REGTM Switching
Regulator Controller 2) Light Load Mode and Continuous Mode Changeable 3) Thermal Shut Down (TSD), Under Voltage LockOut (UVLO), Over Current (detect the peak current) Protection (OCP), Over Voltage Protection (OVP), Short circuit protection with built-in timer-latch 4) Soft start function to minimize rush current during startup 5) Switching Frequency Variable (f=200KHz~600kHz)
6) VQFN032V5050 package 7) Built-in Power good circuit 8) Adjustable to chip set spec by tracking function
●Applications Laptop PC, Desktop PC, LCD-TV, Digital Com...
