Description
BD95514MUV is a switching regulator capable of supplying high current output (up to 4A) 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 H3RegTM control mode technology, yielding the industry’s fastest transient response time against load changes. SLLM (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 tracking functions. This regulator is suited for PC applications.

FEATUREs
1) I Internal low ON-resistance power N-MOSFET (typ:120mΩ)
2) I Internal 5V linear voltage regulator (100mA)
3) Integrated H3RegTM DC/DC converter controller
4) Selectable Simple Light Load Mode (SLLM), 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:It changes depending on the setup condition.)
8) Built-in output discharge function
9) VQFN032V5050 power package
10) Tracking function
11) Internal bootstrap diode
