Product details
Overview
RTKA210030DR0000BU from Renesas Electronics is a 3A, synchronous step-down power module integrating controller, gate drivers, dual MOSFETs, and power inductor in a single 3mm × 3mm × 1.08mm dual flat embedded laminate package. It operates from 2.7V–5.5V input, delivers adjustable output down to 0.6V (±1.5% accuracy), and supports 2MHz default switching with resistor-adjustable range (500kHz–4MHz) for space-constrained point-of-load applications in FPGA and MCU power rails.
For engineers reviewing the RTKA210030DR0000BU datasheet, RTKA210030DR0000BU pinout, RTKA210030DR0000BU application, or RTKA210030DR0000BU equivalent, key selection criteria include its integrated inductor, 100% duty cycle capability (300mV dropout), FPWM/PFM light-load mode selection, and comprehensive protection suite (UVLO, OCP, OVP, OTP, negative current limit).
Technical Context
The RTKA210030DR0000BU implements peak current-mode control with internal slope compensation (440mV/Ts) and transconductance error amplifier (126µA/V internal gain). Its PWM logic uses oscillator-synchronized timing with 105ns minimum on-time and hiccup-mode overcurrent protection triggered at 3.7–6.6A positive peak current limit.
Functional modes are selected via SYNC pin: high (>0.8V) enables forced PWM (FPWM) for low-noise operation; low (<0.4V) enables pulse-skipping (PFM) for light-load efficiency; external 0.5–4MHz clock enables synchronization. Output voltage is set by FB pin resistor divider referencing 0.6V internal bandgap, with soft-start time fixed at 1ms when COMP is tied to SGND.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 3A continuous - supports full-power operation for mid-tier FPGAs and application processors without external heatsinking under typical PCB thermal conditions. |
| Input Voltage Range | 2.7V to 5.5V - compatible with single-cell Li-ion, USB PD, and industrial 3.3V/5V rails without pre-regulation. |
| Output Voltage Range | 0.6V to 5V - covers core voltages for ARM Cortex-A/M cores, DDR memory, and I/O domains via FB resistor divider. |
| Switching Frequency | 500kHz to 4MHz (resistor- or sync-adjustable) - enables optimization between size (higher fSW → smaller capacitors) and efficiency (lower fSW → reduced switching loss). |
| Accuracy & Regulation | ±1.5% total output voltage error over line/load/temperature - ensures stable core supply within ASIC voltage tolerance bands. |
| Protection Features | UVLO (2.2–2.7V), OCP (hiccup mode), OVP, OTP, and negative current limit (−6A to −0.6A) - provides robust fault containment during startup, short-circuit, or reverse-current events. |
| Quiescent Current | 25mA typical at 3.6V input (FPWM), 4.5µA shutdown - minimizes standby power in always-on subsystems. |
Pinout & Package
RTKA210030DR0000BU uses a RoHS-compliant 10-lead dual flat embedded laminate package (3mm × 3mm × 1.08mm, max height 1.15mm) with exposed thermal pad (EPAD) requiring connection to SGND and multiple vias for thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 PGND | Power ground return | Low-inductance path for high-frequency switching current; must be connected near input/output capacitor negatives. |
| 2 FB | Feedback voltage sense | Sets output voltage via resistor divider to 0.6V reference; requires parallel ceramic capacitor for stability at extreme conditions. |
| 3 COMP | Error amplifier output | Internal compensation enabled by tying to VIN; external network required only for custom loop response tuning. |
| 4 SGND | Signal ground reference | Mandatory connection to EPAD; forms reference plane for FB, COMP, and SYNC; separates noise-sensitive analog signals from power paths. |
| 5 VOUT | Regulated power output | Delivers up to 3A; output capacitors must be placed adjacent to minimize loop inductance and ripple. |
| 6 FS | Frequency selection | Resistor-to-SGND sets switching frequency (500kHz–4MHz); open or tied to VIN defaults to 2MHz. |
| 7 EN | Enable control | Active-high logic; drives low to shut down and discharge output; internal pull-down prevents floating state. |
| 8 SYNC | Mode/synchronization | Selects FPWM (high), PFM (low), or external sync (0.5–4MHz square wave); includes 1MΩ internal pull-down. |
| 9 PG | Power-good flag | Open-drain output with 1ms delay after regulation; requires external 10kΩ–100kΩ pull-up to VIN for system sequencing. |
| 10 VIN | Main power input | Accepts 2.7V–5.5V; requires ≥22µF ceramic capacitance placed directly at pin for EMI suppression and transient response. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated inductor + MOSFETs | Eliminates external magnetics and discrete power stage layout complexity; reduces BOM count and PCB area by >40% vs. controller-based solutions. |
| 100% duty cycle operation | Enables ultra-low dropout (typically 300mV) for high-efficiency operation near input rail - critical for battery-powered systems with tight voltage margins. |
| Selectable FPWM/PFM mode | FPWM ensures constant frequency and low EMI in noise-sensitive environments; PFM improves light-load efficiency by skipping pulses without compromising regulation. |
| Soft-stop output discharge | Actively discharges VOUT when EN is pulled low - prevents floating outputs and ensures safe power-down sequencing in multi-rail systems. |
| Dedicated enable & power-good | EN pin enables precise system-level power sequencing; PG provides reliable, delay-compensated status flag for host processor or PMIC coordination. |
| Comprehensive protection suite | Includes UVLO, OCP (hiccup), OVP, OTP, and negative current limit - eliminates need for external fault monitoring circuitry in industrial and medical designs. |

FAQ
What is the recommended input capacitor configuration for RTKA210030DR0000BU?
The RTKA210030DR0000BU requires a minimum of 22µF total ceramic input capacitance placed as close as possible to the VIN and PGND pins. Recommended implementations include one 22µF, 10V, 0603 X5R capacitor (e.g., Murata GRM188R61A226ME15D) or two parallel 10µF units. Additional capacitance improves hold-up time and high-frequency noise suppression, especially under dynamic load conditions.
How is output voltage programmed on RTKA210030DR0000BU?
Output voltage on RTKA210030DR0000BU is set using an external resistor divider connected between VOUT, FB, and SGND. The internal 0.6V reference determines VOUT = 0.6V × (1 + R1/R2). Table 1 in the datasheet provides validated R1/R2 values for common outputs (e.g., 1.2V, 1.8V, 3.3V). A ceramic capacitor (e.g., 680pF) across R2 enhances loop stability under wide temperature and load variations.
Does RTKA210030DR0000BU support external frequency synchronization?
Yes, RTKA210030DR0000BU supports external synchronization via the SYNC pin. Applying a 0.5–4MHz square wave to SYNC overrides the internal oscillator and locks switching to the external clock source. This feature enables EMI reduction through frequency dithering or alignment with system clocks to avoid beat frequencies in sensitive analog or RF sections.
What protection features are implemented in RTKA210030DR0000BU?
RTKA210030DR0000BU integrates UVLO (2.2–2.7V), overcurrent protection with hiccup-mode recovery (3.7–6.6A trip), output overvoltage protection (OVP), over-temperature shutdown (150°C), and negative current limiting (−6A to −0.6A). These functions operate autonomously without external components, ensuring safe operation during input brownouts, output shorts, thermal overload, or reverse-current events.
Can RTKA210030DR0000BU operate at 100% duty cycle, and what is its practical benefit?
Yes, RTKA210030DR0000BU supports true 100% duty cycle operation, achieving typically 300mV dropout voltage. This enables efficient regulation when VOUT approaches VIN - for example, delivering 4.5V from a 5V rail with minimal conduction loss. It eliminates the need for linear post-regulators in battery-powered systems where headroom is limited and efficiency at light loads is critical.
