Product details
Overview
RAA211630GNP#HA0 from Renesas Electronics is a 4.5V–60V input, 3A synchronous step-down DC/DC regulator in a 20-lead QFN (4mm × 3.5mm) package with internal compensation, programmable 200–800kHz switching frequency, and integrated 110mΩ/40mΩ MOSFETs. It delivers stable 0.8V–54V output voltage in industrial power systems requiring high-voltage input tolerance and compact board space.
For engineers reviewing the RAA211630GNP#HA0 datasheet, RAA211630GNP#HA0 pinout, RAA211630GNP#HA0 application, or RAA211630GNP#HA0 equivalent, key selection criteria include its wide VIN range, internal loop compensation, dual-mode (PWM/DCM) operation, EBIAS bias optimization, and thermal robustness up to 125°C junction temperature.
Technical Context
The RAA211630GNP#HA0 employs peak-current mode control with slope compensation and an internal transconductance error amplifier referenced to a 0.8V ±0.5% feedback voltage. Its fixed-frequency PWM operation supports 200–800kHz via external resistor on FS pin, while light-load efficiency is enhanced by discontinuous conduction mode (DCM) and forced PFM/DEM modes.
Protection architecture includes cycle-by-cycle high-side (5A) and low-side (3.6A) current limiting, input UVLO (4.25V rising), output undervoltage lockout (0.4V FB threshold), and thermal shutdown at 155°C with 20°C hysteresis. The device integrates dual LDOs for VCC generation-switching between VIN and EBIAS (3.3–40V) based on voltage level.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5V to 60V - supports direct connection to 24V, 48V, and 60V industrial rails without pre-regulation. |
| Output Current | Up to 3A continuous - enables single-chip supply for FPGA I/O, DSP cores, or multi-rail point-of-load applications. |
| Switching Frequency | Programmable 200–800kHz - allows trade-off between EMI filtering size and transient response speed. |
| Feedback Reference | 0.8V ±0.5% over –40°C to +125°C - ensures tight output regulation across automotive and industrial temperature ranges. |
| Quiescent Current | 95µA typical - minimizes standby power loss in always-on systems such as remote sensors or telecom line cards. |
| Integrated FETs | 110mΩ HS / 40mΩ LS (QFN) - reduces external component count and improves full-load efficiency without discrete MOSFETs. |
| Soft-Start | Fixed 0.5ms internal - prevents inrush current during power-up without requiring external capacitor. |
Pinout & Package
RAA211630GNP#HA0 is housed in a thermally enhanced 20-lead QFN package (4mm × 3.5mm, 0.5mm pitch) with exposed thermal pad connected to AGND. Pin assignments are validated per Renesas R16DS0178EU0101 Rev.1.01, Page 3–4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PGND (Pins 1,13–19) | Power ground return | Source node of integrated low-side FET; must be tied directly to input capacitor ground plane with minimal trace inductance. |
| SW (Pins 2,11,12) | Switch node | Phase node connecting integrated HS/LS FETs; routes to inductor and bootstrap capacitor - critical for EMI and efficiency. |
| VIN (Pins 3,12,20) | Main input supply | Drain of HS FET and input to internal LDO; requires local 10µF+ ceramic decoupling close to pins 3/20. |
| BST (Pin 4) | Bootstrap supply | Supplies gate drive for HS FET; requires 0.1µF X7R 16V ceramic capacitor between BST and SW. |
| EBIAS (Pin 5) | Auxiliary bias input | Enables external bias (e.g., VOUT) to reduce power dissipation; auto-switches when >3.1V. |
| FB (Pin 6) | Feedback input | Inverting input of error amplifier; sets output voltage via resistor divider (e.g., 61.9kΩ/20kΩ for 3.3V). |
| AGND (Pin 7) | Analog ground reference | Reference for FB, PG, FS, SS; must be star-connected to PGND near IC to avoid noise coupling. |
| PG (Pin 8) | Power-good open-drain | Asserts high when VOUT is within ±12% of target; requires external pull-up (≤3.3V) for system sequencing. |
| FS (Pin 9) | Frequency set | Connect to VCC for 400kHz default; tie to AGND via resistor (e.g., 261kΩ) for precise frequency programming. |
| VCC (Pin 10) | Bias supply output | 3.3V ±0.2V regulated output; powers internal logic/gate drivers; requires 1µF ceramic decoupling to AGND. |
| EN (Pin 11) | Enable input | High-voltage tolerant (65V max); active-high with 1.3V threshold; connect to GND via 1MΩ for controlled shutdown. |
Key Features
| Feature | Design Value |
|---|---|
| Internal loop compensation | Eliminates external compensation network - reduces BOM count and layout sensitivity across 200–800kHz range. |
| PFM/DEM light-load mode | Extends battery life or reduces no-load power in always-on systems by lowering switching frequency below 200kHz. |
| External bias (EBIAS) support | Lowers power loss by sourcing IC bias from VOUT instead of VIN - improves efficiency by ~2–3% at light loads. |
| Programmable soft-start (HTSSOP only) | Not applicable to RAA211630GNP#HA0 - this QFN variant uses fixed 0.5ms internal soft-start for predictable startup timing. |
| Thermal protection with hysteresis | Shuts down at 155°C and resumes after 20°C cooldown - prevents thermal runaway in enclosed enclosures or high ambient. |
Applications
| Industrial Power Systems | Distributed Power Supplies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5164QPWPRQ1 | 4.5–65V input, 1A output, external compensation required, no EBIAS pin, 10-pin HTSSOP | Lower current rating limits use to sub-1A loads; lacks integrated bias optimization for efficiency-critical designs. | Select when cost-sensitive, lower-current (<1A), and external compensation is acceptable for tuning loop stability. |
| MPQ4420AGL-A | 3.3–60V input, 2A output, internal compensation, no EBIAS, 12-pin QFN, 500kHz fixed frequency | Fixed 500kHz limits EMI flexibility; missing EBIAS eliminates bias-efficiency optimization at light loads. | Choose for simpler design where fixed frequency suffices and 2A output meets requirement - avoids frequency programming complexity. |
Compared with LM5164QPWPRQ1 and MPQ4420AGL-A, the RAA211630GNP#HA0 uniquely combines 3A capability, programmable frequency, EBIAS-driven efficiency gains, and internal compensation - making it optimal for high-reliability, thermally constrained, and efficiency-sensitive 4.5–60V buck applications.

FAQ
What is the maximum input voltage supported by the RAA211630GNP#HA0?
The RAA211630GNP#HA0 supports an absolute maximum input voltage of 65V, with recommended operation from 4.5V to 60V. This makes it suitable for direct connection to 48V and 60V industrial and telecom distribution buses. Exceeding 60V continuously may impact reliability and is outside the specified operating conditions defined in the R16DS0178EU0101 datasheet.
Does the RAA211630GNP#HA0 require external compensation components?
No, the RAA211630GNP#HA0 features fully internal loop compensation, eliminating the need for external Type-II or Type-III compensation networks. This simplifies design, reduces PCB area, and ensures stable operation across its full 200–800kHz switching frequency range and load conditions without manual tuning.
How does the EBIAS pin improve efficiency in the RAA211630GNP#HA0?
The EBIAS pin allows the RAA211630GNP#HA0 to draw bias power from the output rail (e.g., 5V or 3.3V) instead of the higher input voltage (e.g., 48V), reducing quiescent power dissipation in the internal LDO. When EBIAS >3.1V, the device automatically switches bias sources - improving light-load efficiency by up to 3% compared to VIN-only biasing.
What protection features are integrated into the RAA211630GNP#HA0?
The RAA211630GNP#HA0 integrates cycle-by-cycle high-side (5A) and low-side (3.6A) current limiting, input UVLO (4.25V rising), output undervoltage protection (0.4V FB threshold), thermal shutdown (155°C), and hiccup-mode short-circuit recovery. These features ensure safe operation under fault conditions without requiring external protection circuitry.
Is the soft-start time adjustable on the RAA211630GNP#HA0?
No - the RAA211630GNP#HA0 is the QFN-package variant and implements a fixed 0.5ms internal soft-start. Unlike the HTSSOP version (which supports external capacitor-programmable soft-start via the SS pin), this variant does not expose the SS pin and relies solely on the internal timing circuit for controlled output ramp-up.
