Product details
Overview
RAA2116504GNP#MA0 from Renesas Electronics is a 60V, 5A integrated synchronous buck regulator with adjustable switching frequency (200kHz–2.5MHz), 0.8V–60V input range, and 0.8V output voltage setpoint. It integrates 90mΩ high-side and 37mΩ low-side MOSFETs, internal 1% accurate 0.8V reference, and bidirectional overcurrent protection. It is used in industrial PoL supplies requiring robust 48V/12V step-down with sequencing and spread-spectrum EMI reduction.
For engineers reviewing the RAA2116504GNP#MA0 datasheet, RAA2116504GNP#MA0 pinout, RAA2116504GNP#MA0 application, or RAA2116504GNP#MA0 equivalent, key selection criteria include its 28-pin 4mm×5mm QFN package, programmable soft-start (2ms fixed or capacitor-adjustable), RT-set frequency, MODE/SYNC clock synchronization capability, and comprehensive fault protections including HSOC, LSOC, NOC, OVP, UVP, and OTP.
Technical Context
The RAA2116504GNP#MA0 employs valley current sampling (VCS) control architecture with minimum on-time of 45ns, enabling stable operation at high VIN/VOUT ratios and high frequencies. Its transconductance error amplifier supports both internal compensation (COMP tied to AVCC) and external RC networks for loop tuning.
It features dual bias paths: PVCC can be sourced either from PVIN via internal LDO or from an external 3.15–12V supply on EBIAS-reducing power loss at high input voltages. The MODE/SYNC pin enables three operating modes: fixed-frequency (AGND), spread-spectrum (AVCC), or external clock synchronization (divided-by-2).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5V to 60V - supports wide industrial bus rails including 12V, 24V, 36V, 48V, and 60V systems without pre-regulation. |
| Output Current | 5A continuous - delivers full rated load across -40°C to +125°C junction temperature with thermal derating. |
| Switching Frequency | 200kHz to 2.5MHz - set by RT resistor; default 500kHz when RT = AVCC; enables compact magnetics and noise shaping. |
| Feedback Reference | 0.800V ±1% over temp - provides precise output regulation; enables 3.3V output with standard 1:4 resistor divider. |
| MOSFET rDS(ON) | HS: 90mΩ, LS: 37mΩ - reduces conduction losses and improves efficiency at 5A, especially with EBIAS biasing. |
| Protection Features | Bidirectional OCP (HSOC/LSOC/NOC), OVP (±12%), UVP (−30%), OTP (153°C), UVLO (PVIN/AVCC/EN) - ensures safe operation under fault conditions without external circuitry. |
| Soft-Start Time | 2ms internal (SS = AVCC); programmable via SS capacitor - prevents inrush current and enables controlled power-up sequencing. |
Pinout & Package
RAA2116504GNP#MA0 is housed in a thermally enhanced 28-lead 4mm × 5mm QFN package with exposed thermal pad (EPAD) connected to PGND. The package supports high-power density PCB layouts with multiple vias to internal ground planes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PGND (Pins 1,2,20,21,28) | Power ground return | Low-impedance path for high di/dt switch node currents; must be connected directly to EPAD and large copper pour. |
| PVIN (Pins 3,4,18,19) | Main input power rail | Accepts 4.5–60V; requires local ceramic decoupling (≥10µF) placed adjacent to pins for stability. |
| PHASE (Pins 23–27) | Switch node connection | Connects to inductor and bootstrap capacitor; layout critical for EMI and efficiency; shared high-current path. |
| BOOT (Pin 22) | High-side gate drive supply | Requires 0.1µF ceramic capacitor to PHASE; enables proper high-side FET turn-on above PVIN. |
| RT (Pin 7) | Frequency programming | Resistor to AGND sets fSW from 200kHz–2.5MHz; tie to AVCC for default 500kHz operation. |
| MODE/SYNC (Pin 6) | Operation mode control | AGND = fixed freq; AVCC = spread spectrum; external clock = sync (divided-by-2); enables EMI compliance. |
| SS (Pin 9) | Soft-start timing control | Internal 2ms ramp when tied to AVCC; capacitor to AGND extends ramp time linearly (5µA charge current). |
| V3_DLY (Pin 12) | Startup/shutdown delay | Capacitor to AGND adds programmable delay before soft-start begins or after EN deassertion. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Power Stage | 90mΩ HS + 37mΩ LS MOSFETs eliminate external FETs and gate drivers, reducing BOM count and layout complexity. |
| EBIAS Bias Input | Accepts 3.15–12V external supply to power PVCC LDO, cutting controller quiescent loss by >50% at high VIN (e.g., 48V→3.3V). |
| Valley Current Sampling | Enables stable CCM operation down to 45ns minimum on-time, supporting high VIN/VOUT ratios (e.g., 48V→3.3V @ 500kHz). |
| Programmable Sequencing | V3_DLY and SS pins allow independent control of startup delay, soft-start ramp, and shutdown timing for multi-rail systems. |
| Spread-Spectrum Mode | Reduces peak EMI by dithering fSW around RT-set base frequency when MODE/SYNC = AVCC - aids CISPR-32 Class B compliance. |
Applications
| Industrial PoL Supply | Robotics Motor Drive Logic |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ4333GQ-AEC1-P | 40V max input, 3.5A output, AEC-Q100 qualified; no EBIAS pin or spread-spectrum mode. | Limited to automotive infotainment; lacks 60V rating and programmable sequencing for industrial 48V systems. | Choose for AEC-Q100-compliant automotive designs where 40V input suffices and EMI control is less stringent. |
| TPS54560BQPWPRQ1 | 60V input, 5A, but uses external MOSFETs; no integrated power stage or bidirectional OCP. | Requires gate drivers, current sense, and compensation design; higher BOM cost and layout effort. | Choose when discrete FET selection is required for thermal partitioning or ultra-low quiescent current (<10µA). |
Compared with MPQ4333GQ-AEC1-P and TPS54560BQPWPRQ1, RAA2116504GNP#MA0 uniquely combines 60V/5A integration, EBIAS efficiency optimization, and programmable sequencing in a single 4×5mm QFN-reducing solution size by >40% while enabling robust industrial PoL deployment without redesign.

FAQ
What is the maximum input voltage supported by RAA2116504GNP#MA0?
The RAA2116504GNP#MA0 supports a maximum input voltage of 60V on the PVIN pin, with absolute maximum rating up to 65V. This allows direct operation from 48V industrial buses and withstands ISO 7637-2 load-dump transients common in automotive aftermarket applications. Operation beyond 60V violates recommended conditions and may compromise reliability or safety margins.
Does RAA2116504GNP#MA0 support external clock synchronization?
Yes, RAA2116504GNP#MA0 supports external clock synchronization via the MODE/SYNC pin. When an external clock signal is applied, the internal PWM frequency is synchronized to half the input clock frequency - provided the divided frequency exceeds 110% of the RT-set base frequency. This feature enables deterministic EMI reduction and multi-phase interleaving in complex power systems.
How is the output voltage programmed on RAA2116504GNP#MA0?
The output voltage of RAA2116504GNP#MA0 is programmed using an external resistor divider from VOUT to the FB pin, referenced to the internal 0.800V precision bandgap. For example, a 3.3V output uses R1 = 10kΩ and R2 = 2.43kΩ (VOUT = 0.8 × (1 + R1/R2)). Alternatively, tying FB to AVCC and EBIAS to VOUT enables internal 3.3V regulation without external resistors.
What protection features does RAA2116504GNP#MA0 include?
RAA2116504GNP#MA0 includes undervoltage lockout (PVIN, AVCC, EN), overvoltage protection (OVP ±12% on FB), undervoltage protection (UVP −30%), bidirectional overcurrent protection (HSOC, LSOC, NOC), and overtemperature shutdown (153°C with 30°C hysteresis). All protections trigger automatic hiccup-mode recovery unless latched by sustained fault.
Can RAA2116504GNP#MA0 operate without an external compensation network?
Yes, RAA2116504GNP#MA0 supports internal compensation by connecting the COMP pin directly to AVCC. This configuration provides stable loop response across the full operating range (-40°C to +125°C) without external components. External RC compensation is optional for fine-tuning transient response or adapting to non-standard output capacitors or inductors.
