Product details
Overview
RAA2116054GP3#JA0 from Renesas Electronics is a 4.5V–60V input, adjustable-output DC/DC step-down buck regulator delivering up to 0.5A continuous current with 450kHz fixed switching frequency, internal 600mΩ high-side MOSFET, and peak-current mode control. It integrates soft-start, internal loop compensation, and operates in pulse-skipping mode at light load - deployed in battery-powered handheld tools and industrial power meters.
For engineers reviewing the RAA2116054GP3#JA0 datasheet, RAA2116054GP3#JA0 pinout, RAA2116054GP3#JA0 application, or RAA2116054GP3#JA0 equivalent, key selection criteria include input voltage range (4.5–60V), output current capability (0.5A), feedback reference voltage (0.8V ±2%), thermal shutdown threshold (155°C), and TSOT23-6 package compatibility with space-constrained PCB layouts.
Technical Context
The RAA2116054GP3#JA0 implements peak-current mode control with slope compensation and a 450kHz nominal oscillator, enabling fast transient response and stable operation across wide VIN (4.5–60V) and VOUT (0.8V to Functional protection includes cycle-by-cycle current limiting (0.9A typical peak), input UVLO (4.25V rising threshold with 250mV hysteresis), output undervoltage protection (30% of VFB), and thermal shutdown (155°C with 20°C hysteresis). Soft-start ramps the error amplifier reference from 0V to 0.8V over ~1ms to limit inrush current. RAA2116054GP3#JA0 is housed in a RoHS-compliant TSOT23-6 plastic package (P6.064C), measuring 2.9mm × 1.6mm × 0.85mm with 0.95mm lead pitch. The package features exposed thermal pad for enhanced heat dissipation and is compatible with standard reflow soldering profiles (MSL3). Use Scenario: Utility-grade electricity metering with isolated MCU, ADC, and RF communication modules. IC Role / Device Role / Timing Role: Primary 3.3V or 5V point-of-load regulator supplying metrology SoC and wireless transceiver. Use Value: Wide 4.5–60V input accommodates both AC-derived rectified rails and backup Li-ion/LiFePO₄ batteries; 0.5A output sustains burst-mode RF transmission. Use Scenario: Portable handheld power tools with brushless motor controllers and digital displays. IC Role / Device Role / Timing Role: Secondary regulated supply for MCU, display driver, and sensor interface from main battery pack. Use Value: 60V max input withstands motor back-EMF spikes; pulse-skipping extends runtime in standby; TSOT23-6 saves board area in ergonomic housing. Use Scenario: Remote I/O modules powered via 24V or 48V industrial bus with local regulation. IC Role / Device Role / Timing Role: Local DC/DC converter generating stable 3.3V for FPGA configuration, Ethernet PHY, and isolation drivers. Use Value: Input UVLO (4.25V) prevents brownout operation; thermal shutdown (155°C) ensures reliability in unventilated enclosures. Use Scenario: Loop-powered or battery-operated pressure/temperature transmitters in hazardous areas. IC Role / Device Role / Timing Role: Low-quiescent (300–425µA) regulator powering analog front-end and low-power MCU during sleep cycles. Use Value: 0.8V reference enables accurate 4–20mA loop compliance; small TSOT23-6 footprint fits within explosion-proof sensor housings. The following parts are listed as comparable options for similar DC/DC step-down regulator applications. Compared with RAA2116054GP3#JA0, MP2451DT-LF-Z offers higher switching frequency but narrower input range, while TPS54202DRCT delivers double the output current at the cost of larger footprint and reduced voltage headroom - making RAA2116054GP3#JA0 optimal for 4.5–60V, 0.5A space-constrained industrial applications. RAA2116054GP3#JA0 is available at Aetrix Electronics and suitable for power meters, battery-powered handheld tools, and distributed industrial power systems requiring stable component supply, long-term lifecycle support, and RoHS-compliant packaging. Supply support for RAA2116054GP3#JA0 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs. Renesas Electronics is a global semiconductor leader specializing in microcontrollers, analog power, and connectivity solutions for automotive, industrial, and IoT markets. The RAA211605 series is designed for rugged, wide-input industrial DC/DC conversion - emphasizing simplicity (internal compensation), reliability (multiple fault protections), and compact integration (TSOT23-6) in harsh environments. The RAA2116054GP3#JA0 has an absolute maximum input voltage rating of 65V, with recommended continuous operation up to 60V. Exceeding 60V may reduce reliability or trigger input UVLO behavior outside specification. The device's 4.5–60V operating range makes it suitable for 48V industrial buses and high-voltage battery systems. Always observe derating guidelines in the datasheet for long-term stability. No, RAA2116054GP3#JA0 features fully internal loop compensation - no external Type-II or Type-III compensation network is needed. This simplifies design, reduces BOM count, and improves consistency across production units. The internal compensation is optimized for stability with standard output capacitor ESR and inductance values specified in the datasheet's recommended design table. The BST pin on RAA2116054GP3#JA0 supplies gate drive voltage to the internal high-side MOSFET via a bootstrap capacitor connected between BST and SW. An internal 3V regulator charges this capacitor during low-SW periods. When VIN – VOUT ≥ 3V, the regulator self-refreshes even in pulse-skipping mode; otherwise, ≥5–10mA minimum load is recommended to maintain BST voltage. RAA2116054GP3#JA0 integrates cycle-by-cycle overcurrent protection (0.9A typical), input UVLO (4.25V rising threshold), output undervoltage protection (30% of VFB), thermal shutdown (155°C), and hiccup-mode recovery. These features enable autonomous fault handling without external supervision - critical for unattended industrial and metering applications where reliability is paramount. No - the RAA2116054GP3#JA0 feedback reference is fixed at 0.8V, and the minimum programmable output voltage is 0.8V (achieved when RFB1 = 0Ω). Output voltages below 0.8V are not supported by the internal error amplifier architecture. For sub-0.8V regulation, an external reference or post-regulator stage would be required.Key Specifications

Circuit Role
Design Meaning
BST
Bootstrap supply
Connects to SW via 0.1µF X7R ceramic capacitor to generate gate drive voltage for internal high-side MOSFET.
GND
Power and signal ground
Common return path for internal circuitry, feedback network, and external capacitors; must be low-impedance.
FB
Feedback input
Connects to resistor divider from VOUT to GND; sets output voltage per VOUT = 0.8V × (1 + RFB1/RFB2).
EN
Enable control
High-voltage tolerant (up to 65V); logic-high (>1.275V) enables regulation; pulled low disables output.
VIN

SW
Switch node
Phase node connecting internal high-side FET source, inductor, freewheel diode, and BST capacitor.
Key Features
Feature
Design Value
Internal compensation

Pulse-skipping mode
Maintains high efficiency (<85% at 1mA load with 24VIN/3.3VOUT) under light/no-load conditions.
Integrated soft-start
1ms internal ramp prevents output overshoot and limits input inrush into output capacitors.
Cycle-by-cycle OCP
0.9A peak current limit protects switch during short-circuit or overload without external sensing.
Output UVP with hiccup
Shuts down high-side FET and enters 23ms hiccup cycle if VOUT drops below 30% of setpoint.

Selection Advice
MP2451DT-LF-Z
4.5–36V input, 0.6A output, 2MHz switching, no integrated BST refresh logic.
Limited to ≤36V input; higher fSW requires smaller inductors but increases EMI filtering burden.
Preferred where board space is critical and input voltage never exceeds 36V.
TPS54202DRCT
4.5–28V input, 2A output, 500kHz fSW, external compensation, larger 10-pin WSON package.
Higher current capability but incompatible with >28V inputs; requires more external components.
Chosen when >0.5A load or tighter line/load regulation is required in non-60V systems.
