Product details
Overview
RAA808013GP3#JA0 from Renesas Electronics is a 3A synchronous buck regulator with 2.7V–5.5V input range, integrated high-side (77mΩ) and low-side (42mΩ) MOSFETs, 1.5MHz switching frequency, and Constant On-Time (COT) control architecture. It delivers ultrafast transient response for point-of-load regulation in FPGA, ASIC, and microprocessor power rails.
For engineers reviewing the RAA808013GP3#JA0 datasheet, RAA808013GP3#JA0 pinout, RAA808013GP3#JA0 application, or RAA808013GP3#JA0 equivalent, key selection criteria include its TSOT23-6 package footprint, 0.6V feedback reference with ±3.5% tolerance over –40°C to +125°C, 100% duty cycle capability in dropout, and hiccup-mode OCP/SCP protection.
Technical Context
The RAA808013GP3#JA0 implements a hybrid COT/COFF control scheme: it operates in constant on-time mode across most load conditions for fast line/load transients and seamless transitions into constant off-time or 100% duty cycle as VIN approaches VOUT. Its zero-cross detector enables DCM operation at light loads, while PFM sleep mode reduces quiescent current to 1µA in shutdown.
Internally, the device integrates cycle-by-cycle peak current limiting (4.6A), thermal shutdown at 160°C with 15°C hysteresis, input UVLO (2.65V rising threshold), and open-drain power-good (PG) with 85–90% FB threshold detection. The 0.6V reference is trimmed and stable across temperature, enabling accurate output voltage setting via external resistor divider.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7V to 5.5V - supports single-cell Li-ion, USB-powered, and industrial 3.3V/5V rails without pre-regulation. |
| Output Current | 3A continuous - sufficient for core voltage supply of mid-tier FPGAs and application processors. |
| Feedback Reference | 0.6V ±3.5% (–40°C to +125°C) - enables precise output programming down to 0.6V with minimal drift. |
| Switching Frequency | 1.5MHz typical - allows compact 1µH inductors and low-profile ceramic output capacitors. |
| Internal MOSFET RDS(on) | 77mΩ (HS), 42mΩ (LS) - minimizes conduction loss and improves full-load efficiency above 90% at 1.2V/2A. |
| Protection Features | Cycle-by-cycle OCP (7× limit), hiccup-mode SCP, UVLO, OTP (160°C trip), and PG monitoring - ensures robust operation under fault conditions without external circuitry. |
| Soft-Start Time | 800µs - prevents inrush current and stabilizes startup into pre-biased outputs. |
Pinout & Package
RAA808013GP3#JA0 is housed in a thermally enhanced 6-pin TSOT23 package (P6.064C), featuring an exposed GND pad for improved thermal dissipation and EMI performance. The package measures 2.9mm × 1.6mm × 0.85mm and is RoHS-compliant with matte tin (e3) termination.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (Pin 1) | Enable control input | Logic-level interface (1.2V min high threshold); must be tied to VIN if unused to prevent floating; supports power sequencing. |
| GND (Pin 2) | Power ground | Primary return path for power and control circuits; connects directly to exposed thermal pad for optimal thermal and noise performance. |
| SW (Pin 3) | Switch node | Drain connection of internal high-side MOSFET and source of low-side MOSFET; requires tight layout with minimal loop area to reduce EMI. |
| VIN (Pin 4) | Input supply | Accepts 2.7V–5.5V unregulated input; requires local 1µF MLCC decoupling placed adjacent to pin with direct via to GND plane. |
| PG (Pin 5) | Power-good indicator | Open-drain output pulled low during startup, UVLO, OTP, or FB < 85% of 0.6V; requires external pull-up for system monitoring. |
| FB (Pin 6) | Feedback input | Monitors scaled output voltage; 0.6V reference sets VOUT = 0.6V × (1 + R1/R2); sensitive to noise-must be routed away from SW. |
Key Features
| Feature | Design Value |
|---|---|
| Constant On-Time (COT) Control | Delivers ultrafast transient response (<10µs recovery) with near-constant 1.5MHz frequency across input/output/load variations-no compensation required. |
| 100% Duty Cycle Operation | Maintains regulated output when VIN drops to VOUT level (e.g., 1.2V out from 1.2V input), eliminating brownout risk in battery-critical systems. |
| Light-Load Efficiency Mode | Enters PFM sleep mode below ~100mA, reducing IQ to 1µA and enabling >85% efficiency at 10mA load-ideal for always-on subsystems. |
| Integrated Protection Suite | Combines cycle-by-cycle OCP, hiccup-mode short-circuit protection (3.6ms retry interval), UVLO, and thermal shutdown-eliminates need for external fault management ICs. |
| Pre-Bias Startup Support | Allows safe turn-on into pre-charged output rails without reverse current flow-critical for hot-swap and multi-rail sequencing applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS6286418RTER | 2.5V–5.5V input, 4A output, 2.25MHz switching, 0.6V ref, but no 100% duty cycle support. | Lacks dropout operation-requires higher minimum VIN than RAA808013GP3#JA0 for same VOUT. | Choose when higher frequency and current are needed, and input never falls below VOUT + 0.3V. |
| MP2152GQZ-P | 2.5V–5.5V input, 3A output, 1.5MHz, 0.6V ref, but only 94% max duty cycle and no hiccup-mode SCP. | Cannot sustain regulation at VIN = VOUT; less robust under sustained short-circuit conditions. | Select for cost-sensitive consumer applications where full dropout and hiccup protection are non-critical. |
Compared with TPS6286418RTER and MP2152GQZ-P, RAA808013GP3#JA0 uniquely combines 100% duty cycle, hiccup-mode SCP, and guaranteed 3A operation in a 2.9mm × 1.6mm TSOT23-6 package-making it optimal for space-constrained, high-reliability industrial and medical designs requiring brownout resilience.

FAQ
What is the maximum output current capability of the RAA808013GP3#JA0?
The RAA808013GP3#JA0 delivers up to 3A continuous output current across its full operating temperature range (–40°C to +125°C). This rating is validated with proper PCB thermal design-including direct connection of the exposed GND pad to a solid ground plane-and using recommended 1µH inductors and 22µF ceramic output capacitance. Derating applies above 85°C ambient.
Does the RAA808013GP3#JA0 support pre-bias startup?
Yes, the RAA808013GP3#JA0 supports pre-bias startup, allowing safe turn-on into an already charged output capacitor without reverse current flow. This behavior is confirmed in the datasheet's Functional Description section and validated in Figure 25 (Pre-Bias On, No Load). It is essential for hot-swap and multi-rail sequencing applications where output rails may be powered before the RAA808013GP3#JA0 enables.
What is the feedback reference voltage tolerance over temperature for the RAA808013GP3#JA0?
The RAA808013GP3#JA0 features a precision 0.6V internal feedback reference with ±3.5% tolerance over the full junction temperature range of –40°C to +125°C. This specification is explicitly stated in Section 3.4 (Electrical Specifications) of the datasheet and applies to all operating conditions within the recommended input voltage and load ranges.
Can the RAA808013GP3#JA0 operate with 100% duty cycle, and under what conditions?
Yes, the RAA808013GP3#JA0 supports true 100% duty cycle operation when the input voltage drops to or below the regulated output voltage. In this mode, the high-side MOSFET remains continuously on, passing input voltage directly to the output. This capability is documented in Sections 1 (Overview), 5.3 (100% Duty Cycle), and Figure 1, ensuring regulation during brownout events without dropout.
What protection features are integrated into the RAA808013GP3#JA0?
The RAA808013GP3#JA0 integrates cycle-by-cycle overcurrent protection (OCP) with 4.6A peak limit, hiccup-mode short-circuit protection (SCP) with 3.6ms retry interval, input undervoltage lockout (UVLO) at 2.65V, over-temperature protection (OTP) at 160°C with 15°C hysteresis, and power-good (PG) monitoring. All protections are fully internal-no external components required.
