Product details
Overview
RAA230152GSB#HA0 from Renesas Electronics is a single-channel synchronous step-down DC/DC converter optimized for fixed 5.0 V output, supporting 7 V to 28 V input voltage range, delivering up to 3 A continuous output current with 1.1 MHz fixed switching frequency and integrated power MOSFETs. It targets industrial and communications systems requiring compact, efficient local regulation without battery backup functionality.
For engineers reviewing the RAA230152GSB#HA0 datasheet, RAA230152GSB#HA0 pinout, RAA230152GSB#HA0 application, or RAA230152GSB#HA0 equivalent, key selection considerations include its 8-pin HLSOP package, Auto PFM mode for light-load efficiency, internal soft start (2 ms typ.), discharge circuit for rapid VOUT ramp-down, and thermal shutdown at 165°C.
Technical Context
The RAA230152GSB#HA0 implements a current-mode PWM control architecture with automatic transition between PFM (light load) and PWM (heavy load) modes-no external mode-select pin required. Its internal high-side and low-side MOSFETs feature on-resistances of 220 mΩ and 170 mΩ respectively at 100 mA, enabling high-efficiency conversion across 1 mA–3 A load range.
It integrates a fixed 0.700 V feedback reference, internal phase compensation, and a dedicated discharge switch activated upon EN deassertion to rapidly sink output capacitance. Protection includes latch-type short-circuit protection, auto-recovery thermal shutdown, and under-voltage lockout with 3.9 V turn-on threshold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 7 V to 28 V - supports wide industrial bus rails including 12 V and 24 V systems without pre-regulation. |
| Output Voltage | Fixed 5.0 V - eliminates external resistor divider, simplifying layout and improving accuracy over temperature. |
| Max Output Current | 3 A - sufficient for powering FPGA I/O banks, microcontroller cores, or multi-rail PMIC inputs in space-constrained designs. |
| Switching Frequency | 1.1 MHz (fixed) - enables use of small, low-profile inductors (e.g., 3.3–4.7 µH) and reduces output ripple filtering requirements. |
| Shutdown Current | 1 µA (typ.) - minimizes standby power draw in always-on subsystems such as security sensors or network interfaces. |
| Soft Start Time | 2 ms (fixed) - prevents inrush current and output overshoot during power-up without external timing components. |
| Thermal Shutdown | 165°C (typ., auto-recovery) - protects against sustained overload or poor heatsinking while allowing automatic resumption after cooldown. |
Pinout & Package
RAA230152GSB#HA0 uses an 8-pin HLSOP (Heat Sink Small Outline Package) with exposed thermal pad, optimized for surface-mount assembly and thermal dissipation on standard 4-layer PCBs. The package measures 4.9 mm × 6.0 mm × 1.7 mm and requires GND connection to the exposed pad per Renesas layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VOUT | Feedback node - connects directly to regulated 5.0 V output; used internally to monitor output voltage. |
| 2 | FB | Feedback input - tied internally to fixed 5.0 V reference; left open for fixed-output variants like RAA230152GSB#HA0. |
| 3 | VREG | Internal LDO output - supplies 5.0 V (typ.) bias to internal circuits; requires 1 µF ceramic capacitor to GND. |
| 4 | EN | Enable input - logic-high (>1.3 V) enables operation; logic-low (<0.4 V) places device in 1 µA shutdown state. |
| 5 | GND | Power and signal ground - all five GND pins (pins 5, 6 not listed separately; see full pin map) must be connected to common system ground plane. |
| 6 | LX | Switch node - connects to inductor; carries high di/dt switching current; requires low-inductance routing to minimize EMI. |
| 7 | Boost | Bootstrap supply - connects via 0.1 µF ceramic capacitor to LX to generate gate drive voltage for high-side MOSFET. |
| 8 | VIN | Main power input - accepts 7–28 V; requires ≥10 µF ceramic input capacitor placed close to pin. |
Key Features
| Feature | Design Value |
|---|---|
| Auto PFM/PWM Mode | Automatic efficiency optimization: PFM at light loads (<10 mA), PWM at heavy loads - no external control needed. |
| Integrated Discharge Circuit | Active VOUT discharge path activated on EN deassertion - eliminates need for external MOSFET or resistor network. |
| Synchronous Rectification | On-chip high- and low-side MOSFETs (220 mΩ / 170 mΩ) - improves efficiency by ~8% vs. external diode solutions at 1 A. |
| Fixed 5.0 V Output | No external resistors required - reduces BOM count, layout area, and output voltage drift due to resistor tolerance/TC. |
| Robust Protection Suite | Latch-type SCP, auto-recovery TSD (165°C), and UVLO (3.9 V start) - ensures safe operation under fault conditions without external supervision. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down DC/DC converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS54302DDCR | 3 A, 3.5–28 V input, adjustable/fixed 5.0 V output; 2.0 MHz switching; no integrated discharge circuit. | Lacks active VOUT discharge; requires external circuit for fast ramp-down; higher quiescent current (25 µA). | Choose when higher switching frequency is needed for smaller magnetics, and discharge is handled externally. |
| MP2332GJ-Z | 3 A, 4.5–28 V input, fixed 5.0 V output; 1.1 MHz; includes discharge but no Auto PFM - fixed PWM only. | Fixed PWM mode increases light-load current consumption; lacks automatic efficiency adaptation below 50 mA. | Prefer where constant-frequency EMI profile is mandatory and light-load efficiency is secondary. |
Compared with TPS54302DDCR and MP2332GJ-Z, RAA230152GSB#HA0 uniquely combines fixed 5.0 V output, Auto PFM for sub-1 mA efficiency, and integrated discharge in an 8-pin HLSOP - reducing total solution size and component count for industrial and networking applications.

FAQ
What is the output voltage setting method for RAA230152GSB#HA0?
RAA230152GSB#HA0 features a factory-trimmed fixed 5.0 V output. No external feedback resistors are required - the FB pin is internally connected to the reference and must remain unconnected (open). This eliminates resistor tolerance errors and simplifies PCB layout compared to adjustable variants like RAA230153.
Does RAA230152GSB#HA0 support battery backup functionality?
No. RAA230152GSB#HA0 is part of the RAA23015x series, which excludes the battery backup circuit found in the RAA23014x family. Pins VBB_IN and VBB_OUT are absent from the 8-pin HLSOP package, and the internal backup logic is not implemented. For battery-backed applications, consider RAA230142 or RAA230143 instead.
How does the Auto PFM mode operate in RAA230152GSB#HA0?
RAA230152GSB#HA0 automatically switches between PFM (Pulse Frequency Modulation) at light loads and PWM (Pulse Width Modulation) at heavy loads - no external control signal is needed. At loads below ~10 mA, it reduces switching frequency to maintain >85% efficiency; above ~50 mA, it locks to 1.1 MHz PWM for low-noise, stable regulation.
What thermal performance can be expected from RAA230152GSB#HA0 in an 8-pin HLSOP package?
In a standard 4-layer PCB with 50% copper coverage on outer layers, RAA230152GSB#HA0 delivers 2600 mW maximum power dissipation at TA ≤ 25°C, derating linearly at −26.0 mW/°C above that. With proper thermal pad soldering to GND, it sustains 3 A output at ambient temperatures up to +85°C without thermal shutdown under typical airflow conditions.
Is an external soft-start capacitor required for RAA230152GSB#HA0?
No. RAA230152GSB#HA0 incorporates a fixed 2 ms internal soft-start timer activated upon EN assertion. This eliminates the need for external timing capacitors, reduces component count, and ensures consistent startup behavior across temperature and unit-to-unit variation - critical for repeatable system boot sequences.
