Product details
Overview
RAA2116514GNP#HA0 from Renesas Electronics is a 60V, 5A integrated synchronous buck regulator using Constant On-Time (COT) control. It delivers 0.8V–3.3V output with ±0.6% reference accuracy, 19µA quiescent current at 24V input, and operates across –40°C to +125°C for industrial PoL and battery-powered robotics power rails.
For engineers reviewing the RAA2116514GNP#HA0 datasheet, RAA2116514GNP#HA0 pinout, RAA2116514GNP#HA0 application, or RAA2116514GNP#HA0 equivalent, key selection criteria include its programmable soft-start/sequencing delay, dual-direction overcurrent protection, Diode Emulation Mode for light-load efficiency, and internal 3.3V LDO biasing capability.
Technical Context
The RAA2116514GNP#HA0 implements a COT modulator where on-time is set by PVIN and an external RSET resistor; switching frequency varies inversely with load to minimize losses in DCM. Internal compensation enables Diode Emulation Mode, while external RC on COMP forces CCM operation.
It integrates high-side (90mΩ) and low-side (37mΩ) MOSFETs, supports pre-biased start-up, and features independent high-side OCP (12A), low-side OCP (7.2A), and negative current limit (–3.5A), all with hiccup recovery and thermal shutdown at 153°C.

| Package | 28-pin 4mm × 5mm QFN - thermally enhanced for 5A operation without heatsink |
Pinout & Package
RAA2116514GNP#HA0 is housed in a 28-lead 4mm × 5mm QFN package with exposed thermal pad (EPAD) connected to PGND. The package supports high-power density layouts with low-inductance ground paths via multiple EPAD vias.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PGND (Pins 1,2,20,21,28) | Power ground return | Primary low-impedance path for high-current switch node return; must be tied directly to EPAD |
| PVIN (Pins 3,4,18,19) | Main input supply | Accepts 4.5–60V; requires local ceramic decoupling to PGND for stability |
| PHASE (Pins 23–27) | Switch node | Connects to inductor and bootstrap capacitor; handles full 5A peak currents |
| BOOT (Pin 22) | Bootstrap gate drive | Supplies high-side FET gate drive; requires 0.1µF ceramic to PHASE |
| FB (Pin 11) | Voltage feedback input | Senses output via resistor divider; tied to AVCC for internal 3.3V regulation |
| SS (Pin 9) | Soft-start control | Internal 2ms ramp when tied to AVCC; external capacitor enables programmable timing |
| V3_DLY (Pin 12) | Sequencing delay | Capacitor-to-AGND sets startup/shutdown delay; 5µA charge current defines timing |
| PG (Pin 13) | Power-good indicator | Open-drain output asserting high when FB > 91% VREF and no faults detected |
Key Features
| Feature | Design Value |
|---|---|
| Constant On-Time control | Enables fast transient response and stable operation across wide VIN/VOUT ratios without loop compensation tuning |
| Diode Emulation Mode | Reduces light-load switching losses by entering discontinuous conduction mode with internal compensation only |
| Programmable sequencing delay | V3_DLY pin allows precise power-up/power-down timing coordination across multi-rail systems |
| Integrated 3.3V LDO (PVCC) | Reduces external bias complexity; switches from PVIN to EBIAS source for improved efficiency at high input voltages |
| Dual-direction current protection | Monitors both positive and negative inductor current to prevent reverse conduction damage during load dump or pre-bias conditions |

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 | 4.5–36V input, 3.5A, AEC-Q100 qualified; fixed 500kHz frequency, no programmable delay | Automotive-grade only; lacks 60V rating and sequencing delay for industrial multi-rail use | Choose for automotive production where AEC-Q100 compliance is mandatory and input ≤36V |
| TPS54560BQDDARQ1 | 4.5–60V input, 5A, adjustable frequency (100–2500kHz); no Diode Emulation Mode or internal 3.3V LDO | Requires external bias and compensation; higher quiescent current (40µA) limits battery life | Choose when precise frequency control and external loop tuning are required over light-load efficiency |

FAQ
What is the maximum input voltage rating for RAA2116514GNP#HA0?
The RAA2116514GNP#HA0 has an absolute maximum input voltage rating of 65V on the PVIN pin, with recommended operating range from 4.5V to 60V. This allows safe operation under 48V system transients and automotive load-dump conditions. Exceeding 65V risks permanent damage per the Absolute Maximum Ratings table on page 7 of the R16DS0132EU0200 datasheet.
Does RAA2116514GNP#HA0 support internal 3.3V regulation without external resistors?
Yes, RAA2116514GNP#HA0 supports internal 3.3V regulation by tying the FB pin to AVCC and the EBIAS pin to VOUT. This activates the internal feedback network, eliminating the need for an external resistor divider. The internal reference remains 0.8V, but the feedback topology configures the output to 3.3V with ±1% accuracy over temperature.
How does the soft-start function work on RAA2116514GNP#HA0?
The RAA2116514GNP#HA0 offers both fixed and programmable soft-start. When SS is tied to AVCC, it sources 5µA to an internal node, completing ramp-up in 1.73–2.33ms. For custom timing, an external capacitor from SS to ground sets duration based on 5µA charge current and 0.8V threshold. Soft-start ensures controlled inrush current into output capacitance.
What protection features are integrated into RAA2116514GNP#HA0?
RAA2116514GNP#HA0 integrates undervoltage lockout (UVLO), overvoltage protection (OVP), over-temperature protection (OTP), high-side and low-side overcurrent (HSOC/LSOC), negative overcurrent (NOC), and output undervoltage protection (UVP). All protections trigger hiccup-mode recovery except OTP, which latches until reset via EN or power cycle.
Can RAA2116514GNP#HA0 operate with pre-biased outputs?
Yes, RAA2116514GNP#HA0 supports pre-biased start-up. When VOUT is already charged before enable, the controller avoids reverse inductor current by disabling the low-side FET until the PHASE node voltage aligns with the output. This prevents output voltage droop or overshoot and is confirmed in Figure 40 of the R16DS0132EU0200 datasheet.
