Product details
Overview
RAA230133GSB#HA0 from Renesas Electronics is a synchronous step-down DC/DC converter delivering up to 3A output current with adjustable output voltage (0.8V–6.0V) from a 4.5V–16V input. It integrates high- and low-side MOSFETs, operates at fixed 1.1MHz switching frequency, and features Auto PFM mode for high light-load efficiency-ideal for power rails in smart meters and industrial controllers.
For engineers reviewing the RAA230133GSB#HA0 datasheet, RAA230133GSB#HA0 pinout, RAA230133GSB#HA0 application, or RAA230133GSB#HA0 equivalent, this page provides verified technical context, package mapping, real-world use scenarios, and validated alternative options for embedded power supply design.
Technical Context
The RAA230133GSB#HA0 implements a current-mode PWM controller with integrated 180mΩ high-side and 130mΩ low-side MOSFETs, enabling efficient regulation across wide load ranges. Its Auto PFM mode automatically transitions between pulse-frequency modulation (light load) and pulse-width modulation (heavy load), eliminating manual mode selection.
It includes internal phase compensation, a fixed 2ms soft-start, discharge circuitry for rapid VOUT ramp-down on shutdown, and comprehensive protection: latch-type short-circuit protection, thermal shutdown at 165°C (with 20°C hysteresis), and auto-recovery UVLO (3.9V start / 3.7V stop).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5V to 16V - supports wide-input industrial and telecom power rails without pre-regulation. |
| Output Voltage Range | 0.8V to 6.0V - adjustable via external resistor divider; enables flexible core or I/O rail generation. |
| Max Output Current | 3A continuous - sufficient for FPGA I/O banks, MCU cores, or multi-sensor subsystems. |
| Switching Frequency | 1.1MHz fixed - allows compact external LC filter design with ≤4.7µH inductors and 22µF ceramic output caps. |
| Shutdown Current | 1µA typical - minimizes battery drain in always-on backup or low-power wake-up circuits. |
| Soft Start Time | 2ms fixed - prevents inrush current and output overshoot during power-up without external components. |
| Protection Features | Latch-type SCP, thermal shutdown (165°C), UVLO - ensures robust operation under fault conditions without external supervision. |
Pinout & Package
RAA230133GSB#HA0 uses an 8-pin HLSOP package (Renesas code PLSP0008DB-A) with exposed thermal pad connected to GND for enhanced thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VOUT | Feedback node | Connects to output capacitor; senses regulated voltage for error amplifier loop. |
| 2 - FB | Voltage feedback input | Accepts resistor-divider output; sets target VOUT = 0.7V × (1 + R1/R2). |
| 3 - VREG | Internal LDO output | Provides stable 5.0V (±3%) bias for internal circuitry; requires 1µF ceramic cap to GND. |
| 4 - EN | Enable control input | Active-high logic: drives device into shutdown (<1µA) when pulled low; no internal pull-down. |
| 5 - GND | Power and signal ground | Common reference for all analog/digital blocks; must be tied to exposed pad for thermal integrity. |
| 6 - LX | Switch node | Drives external inductor; requires low-ESR bootstrap capacitor (0.1µF) between LX and BOOST. |
| 7 - Boost | Bootstrap supply input | Supplies gate drive for high-side MOSFET; capacitor forms charge pump with LX node. |
| 8 - VIN | Main power input | Accepts 4.5–16V; requires ≥10µF ceramic input capacitor placed close to pin. |
Key Features
| Feature | Design Value |
|---|---|
| Auto PFM Mode | Automatically switches between PFM (high efficiency at <100mA) and PWM (stable regulation at full 3A); no external control needed. |
| Integrated Discharge Circuit | Activates on EN deassertion to rapidly discharge output capacitance through VOUT pin-eliminates need for external bleed resistors or FETs. |
| Synchronous Rectification | On-chip 180mΩ/130mΩ MOSFET pair reduces conduction loss vs. external diode solutions; improves full-load efficiency by ~8%. |
| Fixed-Frequency PWM Control | 1.1MHz operation enables small magnetics and predictable EMI profile; avoids sub-harmonic instability in current-mode architecture. |
| Robust Protection Suite | Latch-type SCP prevents thermal runaway during sustained overload; thermal shutdown and UVLO provide autonomous fault recovery without system intervention. |

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 | 3A, 3.5–28V input, 570kHz switching, external compensation; no Auto PFM or discharge circuit. | Requires external MOSFETs and compensation network; better suited for higher VIN (>16V) or lower EMI priority designs. | Select if input exceeds 16V or if programmable frequency/compensation is required; not drop-in due to pinout and feature mismatch. |
| MP2332HGTL-Z | 3A, 4.5–28V input, 1.4MHz, integrated PFM/PWM auto-mode, but lacks discharge circuit and has ±3% VREF accuracy vs. RAA230133GSB#HA0's ±2.5%. | Higher max VIN supports wider legacy systems; slightly lower VREF accuracy may impact precision analog rail stability. | Consider for cost-sensitive designs needing 28V tolerance; verify discharge requirement and VREF drift in closed-loop sensor applications. |
Compared with TPS54332DR and MP2332HGTL-Z, RAA230133GSB#HA0 delivers tighter output accuracy, built-in discharge functionality, and optimized 1.1MHz operation for space-constrained industrial boards-making it preferred where BOM reduction, fast shutdown, and precise regulation are critical.

FAQ
What is the output voltage adjustment range for RAA230133GSB#HA0?
The RAA230133GSB#HA0 supports an adjustable output voltage range of 0.8V to 6.0V, set using an external resistor divider on the FB pin. The internal reference voltage is 0.700V (±0.7%), and the formula is VOUT = 0.7 × (1 + R1/R2). This allows precise tailoring of the output rail for MCU cores, sensors, or interface ICs without requiring multiple fixed-output variants.
Does RAA230133GSB#HA0 include integrated MOSFETs?
Yes, RAA230133GSB#HA0 integrates both high-side (180mΩ typical) and low-side (130mΩ typical) power MOSFETs in a synchronous buck topology. This eliminates the need for external discrete FETs, reduces board area, simplifies layout, and improves efficiency-especially at medium to high load currents-compared to controller-only solutions.
How does the Auto PFM mode function in RAA230133GSB#HA0?
RAA230133GSB#HA0's Auto PFM mode automatically transitions between pulse-frequency modulation (PFM) at light loads (<100mA) and pulse-width modulation (PWM) at heavier loads. It detects reverse inductor current to trigger PFM, achieving >85% efficiency at 10mA while maintaining tight regulation and low noise at full 3A-no external pin control is needed, unlike the RAA23012x family.
What protection features are built into RAA230133GSB#HA0?
RAA230133GSB#HA0 includes latch-type short-circuit protection (SCP), thermal shutdown at 165°C (with 20°C hysteresis), and auto-recovery under-voltage lockout (UVLO) that activates below 3.7V and recovers above 3.9V. These protections operate autonomously without host intervention, ensuring safe operation during overloads, overtemperature, or input brownouts.
Is there a discharge function on RAA230133GSB#HA0, and how does it work?
Yes, RAA230133GSB#HA0 includes an integrated discharge circuit activated when the EN pin is pulled low. It turns on an internal switch between VOUT and GND, rapidly discharging output capacitors without external components. This ensures clean power-down sequencing in systems like smart meters or security controllers where residual voltage could disrupt firmware state or cause latch-up.
