Product details
Overview
RAA2113204GP3#JA0 from Renesas Electronics is a 30V, 2A integrated synchronous buck regulator with current-mode constant on-time (COT) control. It integrates high-side (125 mΩ) and low-side (75 mΩ) MOSFETs, delivers 0.765 V reference voltage with ±2% accuracy, supports 4.5–30 V input, and operates in PFM mode under light load. It is used in industrial power supplies and embedded I/O rails where compact, efficient DC-DC conversion is required.
For engineers reviewing the RAA2113204GP3#JA0 datasheet, RAA2113204GP3#JA0 pinout, RAA2113204GP3#JA0 application, or RAA2113204GP3#JA0 equivalent, key selection criteria include minimum on-time (70 ns), minimum off-time (225 ns), internal soft-start (0.8 ms), quiescent current (400 µA), and comprehensive protection (UVLO, LSOC, OUVP, OTP) in a space-constrained 6-pin TSOT23 package.
Technical Context
The RAA2113204GP3#JA0 implements current-mode COT control with internal compensation, enabling fast transient response without external loop components. Its valley-current-based low-side overcurrent (LSOC) detection triggers hiccup-mode recovery upon fault, while the 0.765 V feedback reference enables precise output voltage setting via external resistor divider.
It features programmable VIN UVLO via EN pin resistor divider, accurate enable threshold (1.3 V typ.), and bootstrap regulation with BST UVLO (2.5 V). Thermal shutdown activates at 170°C with 40°C hysteresis, and junction-to-air thermal resistance is 105°C/W in standard layout.
Key Specifications

| Protection Features | UVLO, LSOC, OUVP (hiccup), OTP - ensures robust operation under fault conditions without external circuitry |
Pinout & Package
The RAA2113204GP3#JA0 is housed in a 6-lead TSOT23 package (2.9 mm × 1.6 mm × 0.85 mm), optimized for high-density PCB layouts and thermal performance with θJA = 105°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Power ground reference | Primary return path for all internal circuits and power stage; must be connected to low-impedance ground plane |
| SW | Switch node | Connects directly to inductor; carries high di/dt switching current - requires short, low-inductance trace |
| VIN | Main power input | Supplies IC core and high-side gate driver; requires local 10 µF ceramic decoupling capacitor |
| FB | Feedback input | Senses output voltage via resistor divider; 0.765 V reference sets VOUT = 0.765 × (1 + RFB1/RFB2) |
| EN | Enable control | Logic-level input (1.3 V typ. threshold); supports VIN UVLO programming via resistor divider to GND |
| BST | Bootstrap supply | Connects to SW via 0.1 µF ceramic capacitor to generate gate drive voltage for internal high-side MOSFET |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Power Stage | 125 mΩ high-side + 75 mΩ low-side MOSFETs eliminate external discrete switches and reduce BOM count |

|---|---|---|---|
| TPS562201DRCT | 4.5–17 V input, 2 A, 500 kHz fixed freq., 0.8 V ref, no integrated BST cap control | Limited to ≤17 V input; lacks hiccup-mode OUVP and VIN UVLO programming | Preferred for cost-sensitive 12 V-only designs where 30 V tolerance is unnecessary |
| MP2315GJ-Z | 4.5–30 V input, 2 A, 500 kHz, 0.8 V ref, 130/70 mΩ MOSFETs, no LSOC hiccup | Similar voltage/current specs but uses fixed-frequency PWM only; no PFM light-load mode | Selected when deterministic switching frequency is prioritized over light-load efficiency |

FAQ
What is the maximum input voltage rating for the RAA2113204GP3#JA0?
The RAA2113204GP3#JA0 has an absolute maximum input voltage rating of 32 V, with recommended operation up to 30 V. Exceeding 32 V risks permanent damage. The device includes input undervoltage lockout (UVLO) that disables operation below ~4.3 V (rising) and re-enables only after VIN exceeds ~4.55 V, ensuring clean startup in noisy industrial environments. This behavior is confirmed in the R16DS0082EU0101 datasheet Section 3.4.
Does the RAA2113204GP3#JA0 support adjustable output voltage?
Yes, the RAA2113204GP3#JA0 supports adjustable output voltage from 0.765 V to 16 V using an external resistor divider on the FB pin. The internal 0.765 V reference voltage is compared against the FB node voltage; VOUT = 0.765 × (1 + RFB1/RFB2). Recommended total divider impedance is 5–150 kΩ to balance noise immunity and quiescent current. Table 2 in the R16DS0082EU0101 datasheet provides standard resistor values for common outputs like 1.05 V, 3.3 V, and 5 V.
How does the RAA2113204GP3#JA0 handle overcurrent conditions?
The RAA2113204GP3#JA0 implements low-side overcurrent (LSOC) protection with hiccup-mode recovery. When valley current through the internal low-side MOSFET exceeds ~2.3 A (typ.), the high-side FET is disabled until current falls below the limit. If LSOC coincides with output undervoltage (FB < 500 mV), the device enters hiccup mode: 1 ms active followed by 13 ms shutdown. This protects downstream circuitry without requiring external current-sense amplifiers or latch-off circuitry.
What is the purpose of the BST pin on the RAA2113204GP3#JA0?
The BST pin on the RAA2113204GP3#JA0 supplies gate drive voltage to the internal high-side MOSFET. A 0.1 µF ceramic capacitor must be placed between BST and SW to form a bootstrap circuit. During operation, the BST regulator charges this capacitor when the low-side FET is on. If BST voltage drops below 2.5 V, the high-side FET is skipped until BST recovers - preventing shoot-through and ensuring robust gate drive across duty cycles. This is detailed in Section 6.5 of the R16DS0082EU0101 datasheet.
Can the RAA2113204GP3#JA0 be used in thermally demanding environments?
Yes, the RAA2113204GP3#JA0 is rated for junction temperatures from –40°C to +150°C and includes over-temperature protection (OTP) that shuts down the regulator at 170°C (typ.) with 40°C hysteresis. Its 6-lead TSOT23 package achieves θJA = 105°C/W on standard PCBs and 50°C/W on evaluation boards. Derating curves (Figures 39–40) confirm ≥1.8 A output capability at +85°C ambient with 12 V input, making it suitable for enclosed industrial enclosures without forced airflow.
