Product details
Overview
RAA2116504GNP#HA0 from Renesas Electronics is a 60V, 5A integrated synchronous buck regulator with adjustable switching frequency (200kHz–2.5MHz), 0.8V–(Dmax×VIN) output range, and integrated 90mΩ/37mΩ MOSFETs. It delivers high-efficiency step-down conversion for industrial PoL applications requiring wide input range and robust protection.
For engineers reviewing the RAA2116504GNP#HA0 datasheet, RAA2116504GNP#HA0 pinout, RAA2116504GNP#HA0 application, or RAA2116504GNP#HA0 equivalent, key selection criteria include programmable soft-start (2ms internal or capacitor-adjustable), bidirectional overcurrent protection, spread-spectrum or external clock synchronization via MODE/SYNC, and thermal shutdown at 153°C.
Technical Context
The RAA2116504GNP#HA0 employs valley current sampling (VCS) control architecture in continuous conduction mode (CCM), enabling stable operation with minimum on-time of 45ns for high VIN-to-VOUT ratios. Its transconductance error amplifier supports both internal compensation (COMP tied to AVCC) and external RC network configuration.
Switching frequency is set by an external resistor on RT (200kHz–2.5MHz), with default 500kHz when RT = AVCC. The MODE/SYNC pin enables fixed-frequency operation, spread-spectrum dithering (when tied to AVCC), or external clock synchronization (with ≥110% RT-set frequency), while V3_DLY and SS pins provide independent startup/shutdown delay and soft-start timing control.

Pinout & Package
RAA2116504GNP#HA0 is housed in a thermally enhanced 28-lead 4mm × 5mm QFN package with exposed pad (EPAD) connected to PGND for optimal thermal dissipation. Pin assignments follow JEDEC MO-220 standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PGND (1,2,20,21,28) | Power ground | Primary return path for high-current switch node and IC substrate; must be low-impedance connection to PCB ground plane |
| PVIN (3,4,18,19) | Main power input | Accepts 4.5V–60V supply; requires local ceramic decoupling to minimize high-frequency noise coupling |
| EN (5) | Enable control | Accurate ±5% threshold (1.5V); supports precise power sequencing with coarse/accurate UVLO stages |
| SYNC/MODE (6) | Oscillator control | Selects fixed-frequency, spread-spectrum, or external sync mode; critical for EMI compliance in dense layouts |
| RT (7) | Frequency programming | Resistor-to-AGND sets switching frequency; tie to AVCC for default 500kHz operation |
| SS (9) | Soft-start timing | Sources 5µA; voltage ramp to 0.8V initiates regulation, 1.2V asserts PG - enables controlled output ramp-up |
| COMP (10) | Compensation node | EA output; connect to AVCC for internal compensation or RC network to AGND for custom loop response |
| FB (11) | Voltage feedback | Monitors output via resistor divider; internal 3.3V regulation possible when FB = AVCC and EBIAS = VOUT |
| V3_DLY (12) | Sequencing delay | Capacitor-to-AGND sets startup/shutdown delay; 5µA charge current yields predictable timing for multi-rail systems |
| PG (13) | Power-good indicator | Open-drain output asserting high when SS ≥1.2V and FB ≥91% VREF - used for system enable/disable coordination |
| AGND (14) | Analog ground | Reference for FB, COMP, and internal LDOs; must be separated from PGND and joined at single point |
| AVCC (15) | Analog bias supply | 3.3V LDO output; filtered via 1Ω/1µF RC network to suppress noise affecting precision references |
| EBIAS (16) | External bias input | Accepts 3.15V–12V source (e.g., VOUT); reduces PVCC LDO power dissipation in high-VIN applications |
| PVCC (17) | Gate drive supply | 3.3V output powering internal MOSFET drivers; sourced from PVIN or EBIAS LDO depending on startup sequence |
| BOOT (22) | Bootstrap supply | Drives high-side FET gate; requires 0.1µF ceramic capacitor to PHASE for reliable high-side turn-on |
| PHASE (23–27) | Switch node | Connects to inductor and BOOT capacitor; multiple pins reduce parasitic inductance and improve thermal spreading |

FAQ
What is the maximum input voltage supported by the RAA2116504GNP#HA0?
The RAA2116504GNP#HA0 supports a maximum input voltage of 60V, with absolute maximum rating of 65V on the PVIN pin. Its recommended operating range is 4.5V to 60V, making it suitable for 48V industrial buses and after-market automotive battery systems experiencing load dump transients. Operation above 60V violates recommended conditions and risks permanent damage.
How does the RAA2116504GNP#HA0 implement soft-start, and can it be adjusted?
The RAA2116504GNP#HA0 provides both fixed and programmable soft-start: tying SS to AVCC enables a 2ms internal ramp, while connecting a capacitor from SS to AGND allows user-defined timing based on 5µA charge current and 0.8V regulation threshold. This dual-mode capability ensures compatibility with legacy designs requiring fixed timing and new systems needing precise sequencing control.
Does the RAA2116504GNP#HA0 support external clock synchronization, and what are the requirements?
Yes, the RAA2116504GNP#HA0 supports external clock synchronization via the MODE/SYNC pin. The external clock frequency must exceed 110% of the RT-set switching frequency to ensure reliable synchronization; the internal circuit divides the incoming clock by two before use. This feature enables deterministic EMI reduction and system-level timing alignment in multi-converter applications.
What protection features are integrated into the RAA2116504GNP#HA0?
The RAA2116504GNP#HA0 integrates undervoltage lockout (PVIN and AVCC), overvoltage (OVP at 120% VREF), undervoltage (UVP at 70% VREF), overtemperature (153°C shutdown with 30°C hysteresis), and comprehensive overcurrent protection-including high-side, low-side, and negative current detection. These protections operate independently and trigger hiccup-mode recovery to maintain system integrity during faults.
Can the RAA2116504GNP#HA0 generate a 3.3V output without external feedback resistors?
Yes, the RAA2116504GNP#HA0 supports internal 3.3V regulation by connecting FB to AVCC and EBIAS to VOUT. This configuration bypasses the external resistor divider, reducing component count and layout complexity while maintaining 1% reference accuracy over temperature. It is validated for use in applications where 3.3V is the primary logic rail.
