Product details

Overview

RAA230407GNP#HA0 from Renesas Electronics is a 3-channel synchronous step-down switching regulator with integrated power MOSFETs and 1-channel LDO, delivering preset 3.0 V (ch1), 3.3 V (ch2), adjustable (ch3), and 1.2 V (ch4) outputs. It supports 2.5–5.5 V input, delivers up to 1500 mA per buck channel, and integrates digital soft-start, thermal shutdown (≥150°C), and power-good (PG1) for ch1.

For engineers reviewing the RAA230407GNP#HA0 datasheet, RAA230407GNP#HA0 pinout, RAA230407GNP#HA0 application, or RAA230407GNP#HA0 equivalent, this device serves as a compact, multi-rail PMIC for FPGA I/O banks, microcontroller core/peripheral supplies, and industrial sensor nodes requiring independent channel control, low-power mode (SAVE pin), and robust short-circuit protection with SCP pin timing.

Technical Context

The RAA230407GNP#HA0 implements current-mode PWM control across all three buck regulators (ch1, ch3, ch4), each with integrated high- and low-side MOSFETs (Ron-p/n ≈ 0.4–0.6 Ω), internal phase compensation, and selectable 1.3–2 MHz switching frequency via RT resistor. Ch2 is a standalone LDO with foldback overcurrent protection and 0.5 V dropout at 20 mA.

It features independent ON/OFF control per channel via SHDNB0–SHDNB4 pins, a shared SCP pin enabling timer-latch short-circuit and thermal shutdown (both triggering at SCP = 0.9 V), and dual-mode ch4 output selection (CTL4 = H → 1.2 V fixed; CTL4 = L → external resistor adjustable). The IC operates in normal or low-power mode (15% fOSC) controlled by SAVE pin.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	2.5 V to 5.5 V - Supports single Li-ion or USB-powered systems without pre-regulation.
Buck Output Channels	3 × synchronous step-down (ch1/ch3/ch4) - ch1 preset 3.0 V @ 500 mA; ch3/ch4 adjustable or preset 1.2 V @ 1500 mA each.
LDO Output Channel	1 × ch2 @ 3.3 V / 100 mA - Fixed output with 0.5 V dropout, foldback current limiting, and 1% accuracy.
Switching Frequency	1.3 MHz to 2 MHz (RT-programmable) - Enables compact 2.2–4.7 µH inductors and reduces EMI in noise-sensitive applications.
Protection Features	Timer-latch thermal shutdown (≥150°C), SCP-triggered latch-off, UVLO (1.9–2.3 V start), and digital soft-start - Ensures safe startup and fault containment without external supervision.
Control Interface	Independent SHDNB0–SHDNB4 logic inputs + SAVE/CTL4 pins - Enables precise sequencing, dynamic rail enable/disable, and low-power mode entry without firmware.
Package	32-pin VQFN (5 mm × 5 mm, 0.5 mm pitch, exposed thermal pad) - Optimized for thermal performance in space-constrained PCB layouts.

Pinout & Package

RAA230407GNP#HA0 is housed in a 32-pin VQFN package (5 mm × 5 mm, 0.5 mm pitch) with an exposed thermal pad for enhanced heat dissipation. Pin numbering follows standard top-view layout with pin 1 at top-left corner.

Pin/Terminal	Circuit Role	Design Meaning
VPIN1, VPIN2, VPIN3, VPIN4	Power input for ch1–ch4	Direct connection to respective input rails; VPIN2 powers LDO only; others feed buck stages.
LOUT1, LOUT3, LOUT4	Buck inductor connection	High-current switch node outputs; require low-ESR ceramic capacitors and proper layout for stability.
OUT2	LDO output	Regulated 3.3 V supply; requires ≥2.2 µF ceramic output capacitor for stability.
SHDNB0–SHDNB4	Channel enable/disable control	Active-high logic; internal 400 kΩ pull-down ensures default OFF state if unconnected.
CTL4	Ch4 output mode select	H → 1.2 V fixed (internal resistor); L → adjustable (external R1/R2 divider referenced to 0.8 V).
SCP	Short-circuit/thermal fault timer	Capacitor-connected pin (0.1 µF typical) sets delay before latch-off; must tie to AGND if unused.
PG1	Power-good indicator for ch1	Open-drain output asserting low when ch1 output falls below 90% of set voltage; requires external pull-up.

Key Features

Feature	Design Value
Digital soft-start	Adjustable 2–4 ms startup time (via SS pin resistor) prevents inrush current and output overshoot during power-on.
Low-power mode	SAVE = H reduces ch1/ch3/ch4 switching frequency to 15% of nominal (e.g., ~300 kHz at 2 MHz base), cutting quiescent current to 0.7 mA.
Integrated discharge circuit	Active pull-down on LOUT1/LOUT3/LOUT4/OUT2 during shutdown - eliminates hold-up voltage and enables fast rail collapse for sequencing.
Thermal & short-circuit latch	Single SCP pin coordinates both protections; latches all outputs OFF until SHDNB0 toggle or AVDD reset - prevents repeated fault cycling.
Independent channel control	Five dedicated SHDNB pins allow arbitrary power-up/down sequencing (e.g., ch2 before ch1) without external logic or MCU intervention.

Equivalent & Alternatives

The following parts are listed as comparable options for similar multi-rail PMIC applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS65023RGZR	3 buck + 2 LDO; fixed 1.2/1.8/2.85 V outputs; no adjustable ch3/ch4; 2.25–6.5 V input; 2.25 MHz fSW	Lacks ch3/ch4 adjustability and SAVE low-power mode; higher input voltage range suits 12 V intermediate bus.	Choose TPS65023RGZR when fixed outputs and higher VIN tolerance outweigh need for programmability and ultra-low standby.
ISL9305IRTNZ-T	2 buck + 2 LDO; ch1/ch2 adjustable; 2.7–5.5 V input; 3 MHz fSW; no SCP latch; thermal shutdown only	No shared fault coordination; lacks ch3/ch4 channel count and PG1 monitoring; smaller 4×4 mm QFN.	Choose ISL9305IRTNZ-T for space-constrained designs needing two adjustable bucks and two LDOs, but not full 4-rail sequencing or latch-type protection.

Compared with TPS65023RGZR and ISL9305IRTNZ-T, RAA230407GNP#HA0 uniquely combines four independently controllable rails (3 buck + 1 LDO), adjustable ch3/ch4 outputs, integrated SCP/thermal latch coordination, and low-power mode - making it optimal for FPGA, multi-core MCU, and sensor hub designs demanding flexibility, safety, and efficiency.

FAQ

What output voltages does the RAA230407GNP#HA0 provide?

The RAA230407GNP#HA0 delivers ch1 = 3.0 V (preset), ch2 = 3.3 V (LDO), ch3 = adjustable (external resistor), and ch4 = 1.2 V (preset). Ch4 output mode is selected by CTL4 pin: high for 1.2 V fixed, low for adjustable. All outputs are independently enabled via SHDNB pins, and ch1 includes a power-good (PG1) signal.

How is the switching frequency set on the RAA230407GNP#HA0?

The RAA230407GNP#HA0 switching frequency for ch1/ch3/ch4 is set by an external resistor on the RT pin, ranging from 1.3 MHz to 2 MHz. The approximate formula is fOSC[MHz] = –0.107 × RT[kΩ] + 3.05. For example, a 10 kΩ RT resistor yields ~2 MHz. Frequency accuracy is ±10% over voltage and temperature.

Does the RAA230407GNP#HA0 support power sequencing between channels?

Yes, the RAA230407GNP#HA0 supports precise power sequencing via five independent SHDNB pins (SHDNB0–SHDNB4). Each channel can be enabled/disabled in any order and timing - for example, asserting SHDNB2 before SHDNB1 ensures ch2 (3.3 V LDO) powers up prior to ch1 (3.0 V buck), critical for I/O voltage ordering in FPGAs and MCUs.

What protection features are integrated into the RAA230407GNP#HA0?

The RAA230407GNP#HA0 integrates timer-latch short-circuit protection (SCP), thermal shutdown (≥150°C), under-voltage lockout (UVLO: 1.9–2.3 V start), and digital soft-start. SCP and thermal faults share the same SCP pin and trigger coordinated latch-off of all outputs - requiring SHDNB0 toggle or AVDD reset to recover.

Can the RAA230407GNP#HA0 operate in low-power mode, and how is it activated?

Yes, the RAA230407GNP#HA0 enters low-power mode when the SAVE pin is driven high, reducing ch1/ch3/ch4 switching frequency to 15% of nominal (e.g., ~300 kHz at 2 MHz base) and lowering operating current to 0.7 mA. This mode is intended for light-load conditions (<100 mA per buck channel) and increases output ripple - design trade-offs must be verified.
