Product details
Overview
DA9313-03VK6 from Renesas Electronics is a high-efficiency dual-cell switched capacitor divider IC designed to convert 2S Li-ion battery input (5–10.5 V) to 1S output (VOUT = ½ VIN) with up to 10 A standalone output current and 98% peak efficiency. It integrates power switches, supports I²C configuration, and delivers programmable soft-start, over-temperature/over-current protection, and master/slave parallel operation for 20 A peak output - ideal for ultrabooks and compact portable devices.
For engineers reviewing the DA9313-03VK6 datasheet, DA9313-03VK6 pinout, DA9313-03VK6 application, or DA9313-03VK6 equivalent, key selection considerations include its 43-pin WLCSP package, integrated PVC architecture eliminating external FETs, configurable UVLO/PG thresholds, low-quiescent-current sleep modes, and dual-mode (automatic/fixed-frequency) switching control for dynamic load response in space-constrained battery-powered systems.
Technical Context
The DA9313-03VK6 implements a charge-pump-based switched-capacitor voltage divider topology with synchronous control of internal power switches, enabling direct 2S-to-1S conversion without inductors. Its PVC block operates in automatic frequency mode (adaptive switching) or fixed-frequency mode, with real-time current limiting and thermal supervision via on-die sensors.
It features a dual-domain digital core: one supervises POR, UVLO (configurable 4.6–6.15 V), thermal warning/critical thresholds (110–155 °C), and PG (2.5–5.0 V adjustable), while the other manages I²C register access (0x01–0x33), GPIO control, SLEEP/POWER_DOWN sequencing, and master/slave synchronization via MS_IF and SLAVE_ID pins.

Pinout & Package
DA9313-03VK6 uses a 43-ball Wafer-Level Chip-Scale Package (WLCSP) with RouteEasy™ layout compatibility (0.65 mm pitch). The package supports fine-pitch routing and low-profile assembly for thin mobile platforms.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (9×) | Power Input | Distributed high-current input pads for low-impedance connection to 2S battery rail - reduces voltage drop and thermal stress under 10 A load. |
| VOUT (12×) | Power Output | Multi-pad output node delivering regulated ½ VIN to SoC core rails - enables low-ESR decoupling and current sharing across multiple paths. |
| C1P / C1N / C2P / C2N | Flying Capacitor Interface | Four dedicated terminals for two independent flying capacitors - defines charge-transfer path for switched-capacitor voltage division. |
| BS1 / BS2 | Bootstrap Supply | Gate-drive bootstrap nodes for internal high-side switches - ensures robust turn-on of integrated power MOSFETs during switching cycles. |
| SDA / SCL | I²C Interface | Standard 2-wire bidirectional bus interface for configuration, status readback, and fault logging - requires external pull-ups if enabled. |
| nONKEY / GPIO_0 / GPIO_1 | Configurable I/O | Active-low enable/control inputs and general-purpose pins - support power-up sequencing, interrupt signaling, and system-level coordination. |
| VCORE / AGND / PGND | Supply & Ground | Separate analog core supply (VCORE), quiet analog ground (AGND), and high-current power ground (PGND) - isolates noise-sensitive logic from switching transients. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Power Switches | Eliminates need for external high-side/low-side FETs, gate drivers, and associated layout complexity - reduces BOM count and PCB area by >30% vs discrete solutions. |
| Programmable Soft Start | Configurable ramp rate limits inrush current during power-up - prevents input voltage sag and avoids triggering upstream battery protection circuits. |
| Master/Slave Parallel Operation | Two DA9313-03VK6 units synchronize via MS_IF and SLAVE_ID pins to double peak output current to 20 A - maintains identical VOUT regulation without external current-sharing circuitry. |
| Configurable UVLO & PG Thresholds | VBAT_UV_CRIT (4.6–6.15 V), PVC_PG_ADJ (2.5–5.0 V) set via I²C registers - enables precise battery health monitoring and system-safe shutdown margins. |
| Thermal Supervision | On-die thermal warning (110–140 °C) and critical (125–155 °C) thresholds trigger automatic fault recovery or hard reset - no external thermistor required. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar switched-capacitor voltage converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TPS65987D | USB-C PD controller with integrated 2S-to-1S charge pump (max 6 A); lacks standalone PVC mode and master/slave sync capability. | Targeted at USB-C port power delivery, not primary SoC rail generation; requires companion PMIC for full system power management. | Choose when USB-C host functionality is required alongside voltage conversion - not a direct functional replacement for DA9313-03VK6's standalone PVC role. |
| Analog Devices ADP5600 | High-voltage charge pump with 500 mA max output; supports 2:1, 3:1, and 4:1 ratios but no integrated current sense or thermal protection. | Designed for bias supply generation in RF/industrial systems - insufficient current capacity and protection features for 2S battery-powered computing loads. | Consider only for low-power auxiliary rails; cannot replace DA9313-03VK6 in 10 A core rail applications due to output current and integration gap. |
Compared with TPS65987D and ADP5600, DA9313-03VK6 uniquely combines 10 A standalone output, integrated thermal/current protection, master/slave scalability, and ultra-low-profile WLCSP packaging - making it the only solution qualified for high-current, space-constrained 2S-to-1S conversion in premium portable computing.

FAQ
What is the exact output voltage behavior of the DA9313-03VK6?
The DA9313-03VK6 provides a fixed-ratio output: VOUT = ½ VIN across its full 5–10.5 V input range. This is implemented via a synchronous switched-capacitor architecture with no external feedback components. For example, at VIN = 8.4 V (fully charged 2S Li-ion), VOUT = 4.2 V; at VIN = 6.0 V (partially discharged), VOUT = 3.0 V. The device does not regulate to a fixed voltage - regulation is ratio-based and highly accurate due to matched internal switch timing.
Does the DA9313-03VK6 require external flying capacitors, and what are the recommended values?
Yes, the DA9313-03VK6 requires two external flying capacitors: one connected between C1P/C1N and another between C2P/C2N. Per the datasheet (Table 39), Renesas recommends 2 × 22 µF X5R/X7R MLCCs rated for ≥16 V DC with low ESR (<5 mΩ). These capacitors must be placed adjacent to their respective pins with symmetric, short traces to minimize parasitic inductance and ensure stable charge transfer during switching.
How does master/slave operation work on the DA9313-03VK6, and what signals are required?
Master/slave operation requires two DA9313-03VK6 units: one configured as master (SLAVE_ID = 0), the other as slave (SLAVE_ID = 1). They synchronize via the MS_IF pin (bidirectional clock/data line) and share timing using the internal oscillator. The master controls PVC switching; the slave mirrors its phase and duty cycle. No external clock or current-sense resistor is needed - peak output current scales to 20 A while maintaining tight VOUT matching (<±15 mV).
Can the DA9313-03VK6 operate without I²C connectivity, and what functionality remains available?
Yes, the DA9313-03VK6 operates fully in standalone mode without I²C. Default settings (UVLO = 5.0 V, PG threshold = 3.0 V, auto-frequency mode) are stored in OTP memory. All core functions - power conversion, soft start, thermal/over-current protection, and GPIO-controlled enable - remain active. I²C is optional for dynamic reconfiguration, fault logging, and advanced sequencing; SDA and SCL pins must be pulled to GND if unused.
What thermal protection mechanisms are built into the DA9313-03VK6?
The DA9313-03VK6 integrates two independent thermal supervision levels: a warning threshold (TTH_WARN = 110–140 °C) that asserts nIRQ and logs an event, and a critical threshold (TTH_CRIT = 125–155 °C) that forces immediate HARDRESET. Both thresholds are factory-trimmed and accessible via I²C STATUS/FAULT_LOG registers. No external thermal sensor or circuitry is required - protection activates autonomously based on die temperature.
