Product details
Overview
GS-R415 from SGS-THOMSON Microelectronics is a fixed-output, high-current step-down switching regulator delivering 15.0 V ±4% at up to 4 A, with 19–46 V DC input range, 65 mVpp output ripple, and 85% efficiency. It integrates remote sense, soft start, non-latching overload protection, and crow-bar overvoltage shutdown-used in industrial power supplies requiring stable 15 V rails for motor drivers and PLC I/O modules.
For engineers reviewing the GS-R415 datasheet, GS-R415 pinout, GS-R415 application, or GS-R415 equivalent, key selection factors include its 5 mV/V line regulation, 60 mV/A load regulation, 100 kHz fixed-frequency operation, thermal resistance of 5 °C/W, and compatibility with remote sensing and logic inhibit control.
Technical Context
The GS-R415 employs a fixed-frequency (100 kHz) current-mode PWM architecture with internal MOSFET switching and integrated error amplifier. It uses voltage-mode feedback with remote sense inputs (+Sense/–Sense) to compensate for up to ±250 mV drop per wire, enabling precise regulation at the load under varying cable impedance.
Protection functions are hardware-based: non-latching current limiting triggers at 5–8 A, crow-bar overvoltage activates at Vo × 1.25 (18.75 V), and soft-start limits inrush with 10–35 ms ramp time. Inhibit logic disables regulation when pin 1 is pulled >2 V, with 0.8 V threshold for enable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 15.0 V ±4% - fixed, calibrated at 25°C with Vo+8V input and 1 A load |
| Input Voltage Range | 19–46 V DC - max 46 V inclusive of ripple; absolute max 48 V |
| Max Output Current | 4 A continuous - derated above 60°C case temperature; requires heatsink/forced air at full load ≥36 V |
| Output Ripple | 65 mVpp at 2 A - measured across 20 MHz bandwidth; reduced via external low-ESR input capacitor |
| Efficiency | 85% at 19–46 V input and 1 A load - peak efficiency achieved near mid-input range |
| Line Regulation | 5 mV/V - change in output per volt input variation at 1 A load |
| Load Regulation | 60 mV/A - change in output per ampere load shift at Vo+8V input |
Pinout & Package
GS-R415 uses a metal-cased TO-140 package with integral heatsink and isolated case (electrically floating). Dimensions: 63.5 × 41.3 × 12.7 mm (L×W×H); mounting via four corner pins. Case provides EMI shielding and thermal path to ambient (Rth = 5 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 Inhibit | Logic disable input | High-level (>2 V) disables regulation; low-level (<0.8 V) enables; 500 µA max input current |
| 3 +Input | Main DC input | Accepts 19–46 V DC; requires external low-ESR capacitor (22 µF ceramic or 50 V/2.5 ARMS electrolytic) |
| 4 Input GND | Input return path | Internally tied to pin 8; must be star-connected to minimize ground bounce |
| 8 Output GND | Output return path | Internally connected to pin 4; serves as reference for remote sense and output current return |
| 9 –Sense | Remote load return sense | Connects to load ground point; compensates up to ±250 mV drop; tie to pin 8 if unused |
| 10 +Sense | Remote load high-side sense | Connects to load positive point; enables Kelvin sensing; tie to pin 11 if unused |
| 11 +Output | Regulated DC output | Delivers 15.0 V ±4% at up to 4 A; crow-bar trips at 18.75 V |
Key Features
| Feature | Design Value |
|---|---|
| Remote voltage sensing | Compensates for up to 500 mV total IR drop across load wiring, improving regulation accuracy at point-of-load |
| Non-latching overload protection | Auto-retries after fault clearance with soft-start; avoids system latch-up during transient overloads |
| Crow-bar overvoltage protection | Hardware-triggered short-circuit to ground when output exceeds 18.75 V, preventing downstream component damage |
| Soft-start timing | 10–35 ms controlled ramp prevents inrush current spikes into capacitive loads and reduces stress on input capacitors |
| Logic inhibit interface | CMOS-compatible enable/disable with <0.8 V low and >2 V high thresholds; draws only 500 µA when enabled |
Applications
| Industrial Motor Drive Power Supply | Programmable Logic Controller (PLC) I/O Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current fixed-output step-down regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VPT GS-R415-15 | Same mechanical form, identical electrical specs, but manufactured by VPT post-acquisition; RoHS-compliant revision with updated test flow | Drop-in replacement with same thermal profile and pinout; qualified for aerospace-grade screening (MIL-PRF-38534 Class H) | Select for new designs requiring extended temperature qualification or space-qualified supply chain traceability |
| TDK-Lambda CCG15-400 | 15 V/4 A, 100 kHz, but uses synchronous rectification (vs. diode clamp in GS-R415); 88% efficiency; no crow-bar, only foldback current limit | Lacks hardware overvoltage shutdown; relies on system-level supervision; better light-load efficiency due to sync FET | Prefer where higher efficiency at partial load matters more than fail-safe overvoltage response |
Compared with VPT GS-R415-15, the original GS-R415 offers identical performance but lacks aerospace screening; versus TDK-Lambda CCG15-400, it trades 3% efficiency for deterministic crow-bar protection and legacy compatibility in industrial retrofits.

FAQ
What is the maximum safe operating temperature for GS-R415?
The GS-R415 has an operating case temperature range of –20 to +85 °C. Its thermal resistance is 5 °C/W, so at 4 A output into 15 V (60 W out), with ~10 W dissipation, case rise is ~50 °C above ambient. Thus, ambient must stay ≤35 °C for full-load operation without forced cooling. Derating curves apply above 60 °C case temperature.
Can GS-R415 be paralleled for higher current?
No-GS-R415 lacks current-sharing circuitry or synchronization capability outside the GS-R400VB variant. Pin 5 (Oscillator) and pin 6 (Sync) are not implemented on GS-R415. Attempting parallel operation risks current imbalance and thermal runaway. For >4 A, use a single higher-power module or redesign with active current sharing.
Is remote sense mandatory, and how should unused sense pins be connected?
Remote sense is optional. If unused, pin 9 (–Sense) must be tied directly to pin 8 (Output GND), and pin 10 (+Sense) must be tied directly to pin 11 (+Output). This ensures internal feedback loop closure and prevents instability. Shielding is recommended for sense wires when used, per manufacturer note.
Does GS-R415 support negative output or inverting topology?
No-GS-R415 is strictly a step-down (buck) regulator with positive fixed 15 V output referenced to its output ground. It cannot be configured for inverting, negative, or SEPIC topologies. The internal architecture, pinout, and protection logic assume unidirectional positive output relative to pin 8/4.
