High-Performance Regulators for PCs
Switching Regulator with MOS FET
for DDR-SDRAM Cores
BD95513MUV
No.10030EAT37
●Description
BD95513MUV is a switching regulator capable of supplying high current output (up to 3A) at low output voltages (0.7V~5.0V)
over a broad range of input voltages (4.5V~28V). The regulator features an internal N-MOSFET power transistor for high
efficiency and low space consumption, while incorporating ROHM’s proprietary H³Reg^TM control mode technology, yielding
the industry’s fastest transient response time against load changes. SLLM^TM (Simple Light Load Mode) technology is also
integrated to improve efficiency when powering lighter loads, as well as soft start, variable frequency, short-circuit protection
with timer latch, over-voltage protection, and REF functions. This regulator is suited for PC applications.
●Features
1) Internal low ON-resistance power N-MOSFET
2) Internal 5V linear voltage regulator
3) Integrated H³Reg^TM DC/DC converter controller
4) Selectable Simple Light Load Mode (SLLM^TM), Quiet Light Load Mode (QLLM) and forced continuous mode
5) Built-in thermal shutdown, low input, current overload, output over- and under-voltage protection circuitry
6) Soft start function to minimize rush current during startup
7) Adjustable switching frequency (f = 200 kHz ~ 1000 kHz)
8) Built-in output discharge function
9) VQFN032V5050 package size
10) Tracking function
11) Internal bootstrap diode
●Applications
Mobile PCs, desktop PCs, LCD-TV, digital household electronics
