Product details
Overview
RAA808015BGNP#HA0 from Renesas Electronics is a 5A synchronous buck regulator with 2.7V–5.5V input, 0.6V–5V adjustable output, 2.2MHz fixed switching frequency, integrated 20mΩ/16mΩ MOSFETs, and constant-on-time control for ultrafast transient response in point-of-load applications for FPGAs and microprocessors.
For engineers reviewing the RAA808015BGNP#HA0 datasheet, RAA808015BGNP#HA0 pinout, RAA808015BGNP#HA0 application, or RAA808015BGNP#HA0 equivalent, this part delivers high-efficiency forced-PWM operation, 100% duty cycle dropout support, cycle-by-cycle OCP, hiccup-mode protection, and power-good signaling - critical for low-voltage industrial and battery-powered systems requiring stable regulation under dynamic load.
Technical Context
The RAA808015BGNP#HA0 implements Constant On-Time (COT) control with VIN feedforward and VOUT feedback to maintain near-constant 2.2MHz switching across line, load, and output voltage variations. It operates exclusively in forced PWM mode - disabling PFM/DCM - ensuring predictable frequency and minimal output ripple at light loads.
Its architecture supports seamless transition between COT, constant off-time, and 100% duty cycle modes as VIN approaches VOUT. Internal protection includes cycle-by-cycle peak current limiting (7.8A), hiccup-mode OCP after three faults, thermal shutdown at 160°C with 15°C hysteresis, and UVLO with 2.65V rising threshold and 60mV hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7V to 5.5V - supports single-cell Li-ion, USB PD, and wide-input industrial rails without external pre-regulation. |
| Output Current | 5A continuous - sufficient for core rail of mid-tier FPGAs, DSPs, and application processors. |
| Switching Frequency | 2.2MHz - enables compact 0.47µH inductor and small ceramic output capacitors; reduces EMI filter size. |
| Feedback Reference | 0.6V ±3.5% - sets precise output voltage via external resistor divider; supports down to 0.6V for modern low-VDD cores. |
| MOSFET RDS(on) | 20mΩ (HS), 16mΩ (LS) - minimizes conduction loss; achieves >90% efficiency at 3.3V→1.2V/3A with 0.47µH inductor. |
| Soft-Start Time | 800µs - controls inrush current during startup; supports pre-bias startup without reverse current. |
| Protection Features | Cycle-by-cycle OCP (7.8A), hiccup-mode SCP, UVLO (2.65V/60mV), OTP (160°C/15°C hysteresis) - ensures robust operation in unattended systems. |
Pinout & Package
RAA808015BGNP#HA0 is housed in a Pb-free 10-lead QFN package measuring 2mm × 2.5mm with exposed thermal pad, rated for -40°C to +125°C junction temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW (Pins 1,10) | Switch node | Connects to drain of HS-FET and source of LS-FET; requires low-inductance layout to minimize ringing and EMI. |
| GND (Pins 2,3) | Power ground | Primary return path for high-current switching loop; must be tied directly to exposed thermal pad for thermal and EMI performance. |
| VIN (Pin 4) | Input supply | Accepts 2.7V–5.5V; requires local 10µF ceramic input capacitor placed adjacent to PIN 4 and GND pins. |
| PG (Pin 5) | Power-good indicator | Open-drain output with internal 500kΩ pull-up to VIN; asserts low if FB < 85% of 0.6V or during thermal/overcurrent fault. |
| EN (Pin 6) | Enable control | Active-high logic input; turns on regulator when ≥1.2V; must not float - tie to VIN via 10kΩ if unused. |
| AGND (Pin 7) | Analog ground | Reference ground for FB, VOUT, and internal error amplifier; separate from power GND but connected at single point. |
| FB (Pin 8) | Feedback input | Monitors scaled output voltage; connects to resistor divider (R1/R2) from VOUT to set regulated output per VOUT = 0.6V × (1 + R1/R2). |
| VOUT (Pin 9) | Output voltage sense | Direct connection to output rail for accurate remote sensing; improves load regulation by compensating for PCB trace IR drop. |
Key Features
| Feature | Design Value |
|---|---|
| Forced PWM operation | Eliminates frequency variation and audible noise at light loads; guarantees deterministic timing for sensitive digital loads. |
| 100% duty cycle capability | Maintains regulation when VIN drops to VOUT level - essential for battery discharge scenarios and brownout resilience. |
| Integrated power MOSFETs | Reduces BOM count by eliminating external high-side/low-side switches; simplifies layout and improves thermal coupling. |
| Pre-bias startup support | Enables safe turn-on into pre-charged output rails without reverse current flow - required for hot-swap and multi-rail sequencing. |
| Power-good (PG) with fault reporting | Provides system-level status indication for FPGA configuration, processor reset assertion, and fault logging without external circuitry. |

FAQ
What is the switching frequency of the RAA808015BGNP#HA0?
The RAA808015BGNP#HA0 operates at a fixed 2.2MHz switching frequency, enabling compact magnetics and low-output-ripple designs. This frequency remains stable across input voltage (2.7V–5.5V), output voltage (0.6V–5V), and load conditions due to its constant-on-time architecture with VIN feedforward - a key differentiator from variable-frequency PFM variants like the RAA808015A.
Does the RAA808015BGNP#HA0 support pre-bias startup?
Yes, the RAA808015BGNP#HA0 supports pre-bias startup, allowing safe turn-on into an already charged output rail without reverse current flow. This capability is confirmed in the datasheet's Functional Description section (5.1 Soft-Start) and validated in Figure 50–51 waveforms, making it suitable for hot-swap and multi-rail power sequencing applications where output capacitors may retain residual voltage.
What protection features does the RAA808015BGNP#HA0 include?
The RAA808015BGNP#HA0 integrates cycle-by-cycle peak current limiting (7.8A), hiccup-mode overcurrent protection after three consecutive faults (3.6ms off-time), input undervoltage lockout (2.65V rising threshold with 60mV hysteresis), over-temperature shutdown (160°C with 15°C hysteresis), and power-good fault reporting. These protections are fully documented in Sections 3.5 and 5.8 of the R16DS0226EU0105 datasheet.
Can the RAA808015BGNP#HA0 operate in 100% duty cycle mode?
Yes, the RAA808015BGNP#HA0 supports true 100% duty cycle operation, maintaining regulation when input voltage drops to the output setpoint - critical for battery-powered systems nearing end-of-discharge. This behavior is explicitly described in Section 5.3 ("100% Duty Cycle") and enabled by the internal high-side MOSFET remaining continuously on, as verified in the functional block diagram (Figure 4) and electrical specifications table.
What is the purpose of the VOUT pin on the RAA808015BGNP#HA0?
The VOUT pin on the RAA808015BGNP#HA0 provides remote output voltage sensing, improving load regulation accuracy by compensating for PCB trace resistance between the regulator and load. It connects directly to the load-side of the output capacitor, enabling the controller to adjust switching based on actual delivered voltage - a feature absent in many competing 5A buck regulators and essential for high-precision applications like FPGA core rails.
