Product details
Overview
DA9230-07VZ2 from Renesas Electronics is an ultra-low quiescent current (750 nA), 300 mA I²C-configurable buck regulator in a 1.65 mm × 1.25 mm, 12-pin WLCSP package, designed for battery-powered wearables and remote sensors requiring high light-load efficiency down to 10 µA and dynamic voltage control.
For engineers reviewing the DA9230-07VZ2 datasheet, DA9230-07VZ2 pinout, DA9230-07VZ2 application, or DA9230-07VZ2 equivalent, this page delivers verified electrical specs, real-world use cases, validated alternatives, and supply-chain support for low-power embedded designs.
Technical Context
The DA9230-07VZ2 integrates a synchronous buck converter with PMOS/NMOS power FETs (RON_PMOS = 600–800 mΩ, RON_NMOS = 300–450 mΩ), operates in PFM mode at light loads, and supports 3 MHz fixed-frequency CCM operation. It features integrated UVLO (2.75 V rising threshold), thermal shutdown (125 °C), and cycle-by-cycle over-current protection.
I²C interface (100–400 kHz) enables full configuration of output voltage (0.6–1.9 V in 50 mV steps), DVC profiles, GPO function (power good, event flag, reset pulse), and fault monitoring via STATUS/FAULT registers - all without external components beyond input/output capacitors and inductor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 300 mA continuous DC output supports MCU cores, BLE radios, and sensor subsystems without thermal derating. |
| Quiescent Current | 750 nA total input current (buck enabled, no load) extends battery life in multi-year IoT deployments. |
| Input Voltage Range | 2.5 V to 5.5 V (2.75 V min for startup) accommodates single-cell Li-ion, Li-poly, or two-cell alkaline sources. |
| Output Voltage Range | 0.6 V to 1.9 V programmable in 50 mV steps - covers 0.8 V MCU cores, 1.2 V peripherals, and 1.8 V sensors. |
| Switching Frequency | 3 MHz fixed in CCM mode enables compact 2.2 µH inductor and minimal output capacitance (10 µF). |
| Efficiency @ 10 µA | 81% at 1.8 V output and 10 µA load - critical for always-on wake-up circuits and ultra-low-power sleep states. |
| Protection Features | UVLO (2.75 V rise), thermal shutdown (125 °C), OVP/UVP/OCP, and automatic output discharge ensure robust system-level reliability. |
Pinout & Package
DA9230-07VZ2 uses a 1.65 mm × 1.25 mm, 12-ball Wafer-Level Chip-Scale Package (WLCSP) with 0.4 mm pitch. Pin mapping is validated per Figure 3 and Table 1 of the official datasheet (Rev 3.2, Jun 2023).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD_SYS | Buck input power rail | Primary VIN connection (2.5–5.5 V); tied internally to VDD; supplies power stage and analog core. |
| SW | Buck switch node | Connects to external inductor; carries pulsed high-side/low-side switching current up to 300 mA. |
| PGND | Power ground return | Dedicated low-impedance ground path for buck power loop; must be separated from analog ground. |
| SDA / SCL | I²C bidirectional interface | Standard-mode/fast-mode (100–400 kHz) communication for register read/write and DVC updates. |
| GPO | Configurable digital output | Programmable as power-good indicator, fault event flag, or reset pulse generator (open-drain capable). |
| VBUCK_SNS | Output voltage feedback | Direct connection to regulated VOUT; internal resistor divider sets output voltage (0.6–1.9 V range). |
| IC_EN | Chip enable input | Active-high logic control for full device shutdown (reducing IQ to <100 nA) and controlled start-up sequence. |
| VDD | Analog supply input | Tied to VDD_SYS; powers internal bandgap, regulators, and I²C logic - requires local 1 µF decoupling. |
| GND | Analog ground reference | Reference for internal analog blocks; must be connected to system ground with low-inductance path. |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Voltage Control (DVC) | Enables real-time VOUT adjustment via I²C to match processor DVFS states - reducing system power by >15% in active/idle transitions. |
| Light-Load Efficiency Optimization | PFM mode maintains ≥81% efficiency at 10 µA load - eliminates wasteful linear regulation in sensor wake-up paths. |
| Integrated Fault Monitoring | Status flags (EVENT/STATUS registers) report UVLO, thermal fault, OCP, and OVP events via GPO or I²C polling - enabling autonomous recovery. |
| Configurable GPO Function | GPO pin supports four modes: power-good assertion, interrupt flag, hardware reset pulse, or Hi-Z/pull-down - eliminating external logic. |
| Robust Start-Up Sequence | 3 ms typical start-up time with soft-start (ILIM_PMOS_SO = 350 mA) prevents inrush current and ensures clean VOUT ramp-up. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TPS62840YKGR | Lower IQ (300 nA), same 300 mA rating, but requires external feedback resistors and lacks DVC; 1.4 mm × 1.4 mm DSBGA. | No integrated DVC or GPO event signaling - demands additional GPIO and firmware logic for dynamic scaling. | Choose when absolute minimum IQ outweighs configurability; verify external resistor layout fits space-constrained WLCSP footprint. |
| Analog Devices ADP5302ACBZ-1-R7 | Higher IQ (1.2 µA), 500 mA output, includes integrated LDO; 1.65 mm × 1.65 mm WLCSP with different pinout. | Supports dual-output (buck + LDO) but adds complexity and cost where only single-rail buck is needed. | Prefer when post-regulation noise sensitivity requires LDO filtering; avoid if board area is constrained to DA9230-07VZ2's 1.65 × 1.25 mm outline. |
Compared with TPS62840YKGR and ADP5302ACBZ-1-R7, DA9230-07VZ2 uniquely combines sub-µA quiescent current, I²C-based DVC, and configurable GPO in the smallest WLCSP footprint - delivering system-level power optimization without external components or layout overhead.

FAQ
What is the minimum input voltage required for DA9230-07VZ2 to start up?
The DA9230-07VZ2 requires a minimum input voltage of 2.75 V on VDD_SYS to initiate start-up. Once enabled and regulating, it continues operation down to 2.5 V - a feature critical for maintaining functionality near end-of-battery-life in coin-cell or Li-ion applications. This behavior is confirmed in Table 4 (Recommended Operating Conditions) of the DA9230-07VZ2 datasheet Rev 3.2.
Does DA9230-07VZ2 support dynamic voltage scaling (DVS) or dynamic voltage control (DVC)?
Yes, DA9230-07VZ2 supports Dynamic Voltage Control (DVC) via its I²C interface, allowing real-time adjustment of the output voltage between 0.6 V and 1.9 V in 50 mV steps. This capability enables synchronization with processor DVFS states to minimize system power - a documented feature in Section 10.4.4 and Figure 37–40 of the DA9230-07VZ2 datasheet.
What protection features are integrated into DA9230-07VZ2?
DA9230-07VZ2 integrates under-voltage lockout (UVLO with 2.75 V rising threshold), over-temperature protection (125 °C shutdown with 20 °C hysteresis), cycle-by-cycle over-current protection, output over-voltage and under-voltage protection, and automatic output discharge. These are detailed in Sections 10.2–10.4.8 and Tables 3–4 of the DA9230-07VZ2 datasheet.
Can DA9230-07VZ2 operate without an external feedback resistor network?
Yes, DA9230-07VZ2 does not require external feedback resistors. Its output voltage is set digitally via I²C registers (BUCK_CFG) using an internal resistor divider referenced to VBUCK_SNS. This eliminates layout area, BOM cost, and tolerance drift - a key advantage confirmed in Section 10.4.1 and Table 11 of the DA9230-07VZ2 datasheet.
What is the switching frequency of DA9230-07VZ2 in continuous conduction mode?
The DA9230-07VZ2 operates at a fixed 3 MHz switching frequency in continuous conduction mode (CCM), as specified in Table 6 (Electrical Characteristics) of the datasheet. This high frequency enables use of small 2.2 µH inductors and reduces output ripple without increasing filter capacitor size - essential for space-constrained wearables and hearables.
