Product details
Overview
RAA230132GSB#HA0 from Renesas Electronics is a single-channel synchronous step-down DC/DC converter optimized for fixed 5.0 V output, supporting 4.5 V to 16 V input voltage and delivering up to 3 A continuous load current. It integrates high- and low-side power MOSFETs, operates at a fixed 1.1 MHz switching frequency, and features Auto PFM mode for high light-load efficiency-ideal for industrial surveillance cameras and smart meter power rails.
For engineers reviewing the RAA230132GSB#HA0 datasheet, RAA230132GSB#HA0 pinout, RAA230132GSB#HA0 application, or RAA230132GSB#HA0 equivalent, this page delivers verified technical context, package-specific pin functions, real-world application mappings, and validated alternative options for system-level power design.
Technical Context
The RAA230132GSB#HA0 implements a current-mode PWM control architecture with integrated 180 mΩ high-side and 130 mΩ low-side MOSFETs, enabling efficient conversion across its full 4.5–16 V input range. Its Auto PFM mode automatically transitions between pulse-frequency modulation (light load) and pulse-width modulation (heavy load), eliminating external mode-select logic.
It includes internal soft-start (2 ms fixed), discharge circuitry (100–200 Ω on-resistance), thermal shutdown (165 °C detect, 20 °C hysteresis), latch-type short-circuit protection, and auto-recovery UVLO (3.9 V start / 3.7 V stop). The device lacks battery backup circuitry-distinguishing it from RAA23012x variants-and uses an 8-pin HLSOP package with exposed thermal pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5 V to 16 V - supports wide-range industrial supplies including 12 V rail and 15 V PoE-derived inputs. |
| Output Voltage | Fixed 5.0 V - no external feedback resistors required; ±2.5 % accuracy over line/load/temperature. |
| Max Output Current | 3 A continuous - sufficient for powering SoCs, sensors, and communication interfaces in embedded systems. |
| Switching Frequency | 1.1 MHz fixed - enables compact LC filter design with ≤4.7 µH inductors and ≥22 µF ceramic output capacitors. |
| Shutdown Current | 1 µA typical - ensures ultra-low quiescent power during system sleep or standby modes. |
| Soft Start Time | 2 ms fixed - prevents inrush current and output overshoot without external timing components. |
| Thermal Shutdown | 165 °C detect with 20 °C hysteresis - protects against sustained overload or poor PCB thermal layout. |
Pinout & Package
RAA230132GSB#HA0 uses the 8-pin HLSOP package (Renesas code PLSP0008DB-A) with exposed thermal pad connected to GND for enhanced thermal performance. Pin functions are validated per R18DS0015EJ0100 Rev.1.00.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: VOUT | Feedback sense node | Connects to output capacitor; monitors regulated 5.0 V rail for closed-loop control. |
| 2: FB | Feedback input | Internally tied to fixed 5.0 V reference; leave open for fixed-output operation. |
| 3: VREG | Internal LDO output | Supplies 5.0 V (±3%) to internal circuitry; requires 1 µF ceramic capacitor to GND. |
| 4: EN | Enable control input | Active-high logic: connect to VIN for always-on, or microcontroller GPIO for sequencing. |
| 5: GND | Power and signal ground | Common return for power stage, control logic, and thermal pad; must be low-impedance. |
| 6: LX | Switch node | Drives external inductor; requires low-ESR bootstrap capacitor (0.1 µF) to Boost pin. |
| 7: Boost | Bootstrap supply input | Connected to LX via 0.1 µF ceramic capacitor; sustains high-side gate drive during conduction. |
| 8: VIN | Main power input | Accepts 4.5–16 V; requires ≥10 µF input capacitance placed close to pin for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Auto PFM/PWM seamless transition | Eliminates manual mode selection; maintains >85 % efficiency from 1 mA to 3 A load without external circuitry. |
| Integrated power MOSFETs | 180 mΩ high-side + 130 mΩ low-side FETs reduce BOM count and layout complexity versus controller+external FET solutions. |
| Discharge circuit | 100–200 Ω on-resistance rapidly discharges output caps when EN = low-critical for safe hot-plug or reset sequencing. |
| Latch-type short-circuit protection | Halts switching immediately upon FB voltage collapse; requires EN toggle or VIN cycle to recover-prevents thermal runaway. |
| Thermal and UVLO protection | Auto-recovery UVLO (3.9 V start) and thermal shutdown (165 °C) ensure robust operation under brownout or overload conditions. |
Applications

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 |
|---|---|---|---|
| TPS54332DR | 3 A, 3.5–28 V input, adjustable output (0.8–26 V), 1 MHz, no Auto PFM - requires external feedback resistors. | Used where output voltage flexibility or higher VIN tolerance is needed; lacks integrated discharge circuit. | Select when adjustable VOUT or >16 V input is required; verify loop compensation for 5.0 V fixed use. |
| MP2332GJ-Z | 3 A, 4.5–28 V input, fixed 5.0 V option, 500 kHz, Auto PFM - smaller 8-pin SOIC package, lower thermal rating (2.2 W). | Suitable for space-constrained consumer devices; not rated for extended 85 °C industrial ambient. | Prefer for cost-sensitive, non-industrial designs with relaxed thermal requirements and footprint constraints. |
Compared with RAA230132GSB#HA0, TPS54332DR offers wider input range but adds BOM complexity and lacks discharge functionality, while MP2332GJ-Z matches the fixed 5.0 V output and Auto PFM but trades thermal robustness for smaller size-making RAA230132GSB#HA0 optimal for thermally demanding industrial 5.0 V rails.

FAQ
What is the output voltage configuration of RAA230132GSB#HA0?
The RAA230132GSB#HA0 is factory-configured for fixed 5.0 V output. It does not require external feedback resistors-FB pin is internally connected to the 5.0 V reference and must be left open. This eliminates tuning errors and simplifies layout compared to adjustable variants like RAA230133. The output accuracy is ±2.5 % over line, load, and temperature ranges per the R18DS0015EJ0100 datasheet.
Does RAA230132GSB#HA0 support battery backup functionality?
No, RAA230132GSB#HA0 does not include battery backup circuitry. That feature is exclusive to the RAA23012x series (e.g., RAA230121/122/123), which integrate VBB_IN/VBB_OUT pins and internal diode-or logic. RAA230132GSB#HA0 is a dedicated step-down converter with only VIN, VOUT, EN, LX, Boost, VREG, FB, and GND pins-confirmed in the Pin Function table on Page 5 of R18DS0015EJ0100.
What thermal derating applies to RAA230132GSB#HA0 in an 8-pin HLSOP package?
In the 8-pin HLSOP package (PLSP0008DB-A), RAA230132GSB#HA0 has a maximum power dissipation of 2600 mW at TA ≤ +25 °C, decreasing by −26.0 mW/°C above that temperature. At +85 °C ambient, usable power drops to ~1040 mW. Proper PCB design-including connecting the exposed thermal pad to a ≥2 cm² GND copper area-is essential to maintain 3 A output capability across the full −40 °C to +85 °C operating range.
How does the Auto PFM mode operate in RAA230132GSB#HA0?
RAA230132GSB#HA0 operates exclusively in Auto PFM mode-unlike RAA23012x, it has no x_AutoPFM pin. It automatically switches between PFM (at light loads, improving efficiency below ~100 mA) and PWM (at heavy loads, ensuring tight regulation above ~500 mA). This transition is based on inductor current zero-crossing detection and requires no external configuration, as specified in Section 13 of R18DS0015EJ0100.
What protection features are implemented in RAA230132GSB#HA0?
RAA230132GSB#HA0 integrates latch-type short-circuit protection (SCP), auto-recovery thermal shutdown (165 °C detect), and auto-recovery under-voltage lockout (UVLO: 3.9 V start / 3.7 V stop). It also includes a dedicated discharge circuit (100–200 Ω) that actively sinks output capacitance when EN is pulled low. These protections are fully documented in Sections 17–18 of the R18DS0015EJ0100 datasheet and require no external components to function.
