Product details
Overview
RTKA223010DE0030BU from Renesas Electronics is a universal-input AC/DC buck switching regulator with integrated 700V MOSFET, delivering up to 10W output power at 12V/0.49A (230VAC), supporting output voltages as low as 3.3V, and achieving ultra-low no-load standby power of <15mW. It operates in constant off-time mode above ~45kHz under heavy load and transitions to PFM for light-load efficiency, targeting bias power supplies in home appliances and IoT edge nodes.
For engineers reviewing the RTKA223010DE0030BU datasheet, RTKA223010DE0030BU pinout, RTKA223010DE0030BU application, or RTKA223010DE0030BU equivalent, key selection criteria include its 700V drain rating, programmable PFM for COUT optimization, hiccup-mode fault protection (SCP/OLP/OVP/OTP), and SOIC-7 package compatibility with high-voltage AC/DC buck topologies requiring minimal external components.
Technical Context
The RTKA223010DE0030BU implements a high-side floating buck topology with internal VCC bootstrap supply, using feedback-sampled output voltage to control peak current via an error amplifier. Its dual-mode operation-constant off-time (22–26 µs) above audible range and adaptive PFM below 1 kHz-ensures noise-free operation while maintaining regulation across 3.3–24V outputs.
Protection logic integrates input brownout detection, open-feedback sensing, and thermal shutdown at 150°C with 30°C hysteresis. Fault responses use controlled hiccup timing: OLP triggers a 1024-cycle timer before VCC discharge to 4V and restart; SCP activates after four consecutive cycles exceeding 1.4A peak current, followed by VCC recharge to 5.9V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 85–265VAC universal input; supports global mains without manual selection. |
| Output Power | Up to 10W at 12V/0.49A (230VAC); derated to 9.6W at 24V/0.4A (230VAC). |
| Standby Power | <15mW at no load; enabled by PFM mode and <75µA quiescent current. |
| Drain Breakdown | 700V rated; eliminates need for external HV MOSFET in compact AC/DC designs. |
| Switching Control | Hybrid COT + PFM: fixed 45kHz heavy-load frequency; variable sub-1kHz light-load frequency. |
| Protection Features | Hiccup-mode SCP, OLP, OVP, OTP, and open-feedback detection-no latch-off, enabling automatic recovery. |
| Efficiency | Up to 80% at full load (12V/0.5A, 230VAC); optimized by frequency dithering for EMI reduction. |
Pinout & Package
RTKA223010DE0030BU is housed in a 7-lead SOIC package with exposed thermal pad (SOIC-7EP), optimized for high-voltage isolation and thermal dissipation in compact AC/DC converters.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | IC supply voltage input | Internal LDO input; starts at 5.9V, shuts down at 3.7–4.4V UVLO; supports backfeed from output. |
| FB | Feedback voltage sense | Monitors RC-sampled output; reference = 2.5V ±0.11V; triggers PFM entry when VFB drops to 0.85V. |
| DRAIN | Integrated MOSFET drain | 700V-rated high-side switch node; connects to bulk capacitor and primary side of buck inductor. |
| SOURCE | Integrated MOSFET source | Common source terminal (pins 5–8 tied internally); forms return path for switching current and FB sampling. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable PFM | CFB1 capacitor sets no-load switching interval-enables precise standby power tuning from 5mW to 15mW. |
| Frequency Dithering | Spreads EMI spectrum around 45kHz fundamental; reduces peak conducted emissions without added filtering. |
| Soft Start-Up | Controlled VCC ramp and variable off-time prevent inrush current spikes during cold start at 85VAC or 265VAC. |
| Low EMI Layout Support | Small-source loop design (pins 5–8) and dedicated VCC/FB decoupling pads minimize parasitic ringing and ground bounce. |
| Hiccup Timing Control | CVCC value directly sets OLP hiccup delay (e.g., 1µF → ~100ms); enables predictable fault response without external timers. |
Applications
| Smart Home Sensors | Industrial Metering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar AC/DC buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP174G-P | 650V MOSFET; fixed 65kHz frequency; no PFM mode; 25mW typical no-load power. | Lacks programmable light-load optimization; higher standby power limits use in ErP-compliant designs. | Select when fixed-frequency EMI profile is preferred and >20mW standby is acceptable. |
| LNK3206D | 725V MOSFET; primary-side regulation; no FB pin; 17mW no-load power; requires transformer design. | Isolated flyback architecture increases BOM cost and size; unsuitable for non-isolated buck topologies. | Select only when reinforced isolation is mandatory and transformer-based design is already established. |
Compared with MP174G-P and LNK3206D, RTKA223010DE0030BU uniquely combines 700V integration, PFM programmability for sub-15mW standby, and non-isolated buck simplicity-making it optimal for cost-sensitive, space-constrained, and energy-certified AC/DC bias rails.

FAQ
What is the maximum output voltage supported by the RTKA223010DE0030BU?
The RTKA223010DE0030BU supports output voltages up to 24V, as confirmed by Table 1 (Maximum Output Current) and electrical specifications listing 24V as a valid output setting. At 24V/0.4A (230VAC), it delivers 9.6W output power while maintaining regulation and thermal safety within ambient limits of 85°C.
Does the RTKA223010DE0030BU require an external startup resistor?
No, the RTKA223010DE0030BU integrates a high-voltage current source for VCC charging during startup, eliminating the need for an external startup resistor. The IC begins switching once VCC reaches 5.9V, and the internal HV source disables automatically-reducing component count and improving reliability over resistor-based solutions.
How does the RTKA223010DE0030BU achieve <15mW no-load power consumption?
The RTKA223010DE0030BU achieves <15mW no-load power through three synergistic features: PFM mode that reduces switching frequency below 1kHz, ultra-low 75µA quiescent current, and minimized peak current (120mA minimum) during light-load operation-all coordinated by the internal feedback comparator and timing logic.
Can the RTKA223010DE0030BU be used in a non-isolated buck configuration with 230VAC input?
Yes, the RTKA223010DE0030BU is specifically designed for non-isolated buck topologies with universal AC input (85–265VAC). Its 700V drain rating, integrated MOSFET, and high-side floating architecture enable direct connection to rectified mains-verified in Figure 1 and Application Topologies section of the R16DS0233EU0101 datasheet.
What is the purpose of the CFB1 capacitor in the RTKA223010DE0030BU circuit?
The CFB1 capacitor sets the no-load switching interval in PFM mode by controlling the discharge rate of the feedback sampling network. As described in Section 7.3, its value directly determines light-load standby power-larger CFB1 yields longer off-times and lower average power, enabling precise tuning of RTKA223010DE0030BU's <15mW target.
