Product details
Overview
SIC467ED-T1-GE3 from Vishay Siliconix is a 6 A, 4.5 V to 60 V input synchronous buck DC/DC converter with integrated high-side and low-side MOSFETs, adjustable 0.8 V output, internal compensation, and 2 MHz max switching frequency-designed for industrial computing power rails requiring fast transient response and ultra-low light-load power loss.
For engineers reviewing the SIC467ED-T1-GE3 datasheet, SIC467ED-T1-GE3 pinout, SIC467ED-T1-GE3 application, or SIC467ED-T1-GE3 equivalent, this page delivers verified electrical parameters, validated pin functions, confirmed protection features (OCP/UVP/OVP/OTP), real-world application context, and two rigorously cross-checked alternative parts for design continuity.
Technical Context
The SIC467ED-T1-GE3 implements voltage-mode constant-on-time (COT) control with adaptive zero-current detection, enabling diode emulation and frequency foldback in light-load conditions. Its internal ramp generator eliminates need for external ESR networks, and it supports pre-bias start-up with output voltage tracking.
It integrates dual N-channel MOSFETs optimized for 98 % peak efficiency at 24 VIN/12 VOUT, uses an internal 5 μA soft-start current source, and provides programmable valley current limit (5 A/7.5 A/10 A) via ILIMIT pin configuration-without requiring external current-sense resistors.
Key Specifications

| Input Voltage Range | 4.5 V to 60 V-supports wide industrial and telecom input rails without external regulators. |
| Output Voltage | Adjustable down to 0.8 V-enables core logic, FPGA, and ASIC supply with ±1 % accuracy over -40 °C to +125 °C. |
| Switching Frequency | 100 kHz to 2 MHz-set by external resistor on fSW pin; enables optimization of size vs. efficiency trade-offs. |
| Valley Current Limit | 5 A / 7.5 A / 10 A-selected by ILIMIT pin tied to AGND / floating / VDD per Electrical Specifications table. |
| Efficiency | 98 % peak-achieved with integrated low-RDS(on) MOSFETs and COT control minimizing conduction & switching losses. |

Pinout & Package
Package: PowerPAK® MLP55-27L (5 mm × 5 mm, 27-pin lead-free QFN with exposed thermal pad).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VCIN | Internal regulator bias supply | Accepts 4.5–60 V input; powers VDD/VDRV LDOs-decoupled with 0.1 μF cap to AGND. |
| 2 PGOOD | Open-drain power-good flag | Asserts high-impedance when VFB is within ±10 % of setpoint; requires external 10 kΩ pull-up. |
| 3 EN | Enable control | High-voltage compatible (0–60 V); internal weak pull-down prevents floating startup. |
| 4 BOOT | High-side gate driver bootstrap | Connects via RC network to PHASE; 4.7 Ω min series resistor recommended for stability. |
| 5,6 PHASE | High-side MOSFET source / low-side drain node | Power switch node return path-must be routed with low-inductance copper to PGND. |
| 7,8,29 VIN | Main power stage input | Drain of high-side MOSFET; connect bulk decoupling caps directly to PGND pads. |
| 9,10,11,17,30 PGND | Power ground | High-current return for MOSFETs and input/output capacitors-separate from AGND. |
| 12,13,14 SW | Switch node | Connects to inductor; high dv/dt node-requires tight layout and minimal trace length. |
| 15 GL | Low-side gate driver output | Direct drive signal to low-side MOSFET gate-no external driver needed. |
| 16 VDRV | Gate driver supply | Internal LDO output (4.75–5.55 V); decoupled with 4.7 μF cap to PGND. |
| 19 SS | Soft-start timing | Charged by internal 5 μA current source; capacitor value sets ramp time per CSS = (0.8 V × tSS) / 5 μA. |
| 20 VOUT | Output voltage sense point | Internal ripple injection reference-connects directly to output capacitor positive terminal. |
| 22 VFB | Feedback input | Compares against 0.8 V reference; connects to resistor divider for output voltage programming. |
| 23,28 AGND | Analog ground | Reference for feedback, timing, and protection circuits-shorted together and connected under IC body. |
| 24 fSW | Frequency setting | Resistor-to-AGND sets fSW: RfSW = (VOUT × 1.9×10−10) / fSW. |
| 25 ILIMIT | Current limit selection | Tie to AGND (5 A), float (7.5 A), or VDD (10 A)-configures valley OCP threshold per SiC467 spec table. |
| 26 VDD | Bias supply output | Internal LDO output (4.55–5.3 V); decoupled with 1 μF cap to AGND. |
| 27 MODE | Operating mode control | Resistor-to-AGND selects power-save mode and VDRV regulator state (see Table 1). |
Key Features
| Feature | Design Value |
|---|---|
| Wide input range | 4.5 V to 60 V single-supply operation-eliminates need for pre-regulators in 24 V/48 V industrial systems. |
| Internal compensation | Stable with any output capacitor type-including all-ceramic designs-no external ESR network required. |
| Ultrafast transient response | Minimizes output capacitance requirement while maintaining < ±1 % regulation during load steps up to 6 A. |
| Light-load efficiency | 4 μA shutdown current and diode emulation mode reduce no-load losses-critical for always-on IoT nodes. |
| Configurable protection | User-selectable OCP thresholds and auto-retry hiccup mode for UVP enable robust field deployment. |

FAQ
What is the maximum switching frequency supported by the SIC467ED-T1-GE3?
The SIC467ED-T1-GE3 supports a programmable switching frequency range of 100 kHz to 2 MHz, set by an external resistor on the fSW pin. At 24 VIN/12 VOUT, it achieves stable 2 MHz operation per Vishay's typical performance curves-enabling compact magnetics and reduced output ripple without sacrificing efficiency.
How does the SIC467ED-T1-GE3 achieve stability with all-ceramic output capacitors?
The SIC467ED-T1-GE3 uses an internal ramp generator synchronized to switching events, eliminating dependency on capacitor ESR for loop stability. This allows use of low-ESR ceramic capacitors without external compensation-verified across 10 μF to 1000 μF ranges in Vishay's application notes and evaluation board testing.
What are the three valley current limit options for the SIC467ED-T1-GE3 and how are they selected?
The SIC467ED-T1-GE3 offers 5 A, 7.5 A, or 10 A valley current limit settings via the ILIMIT pin: tie to AGND for 5 A, leave floating for 7.5 A, or connect to VDD for 10 A. These values are explicitly specified in the Electrical Specifications table for SiC467 and confirmed in the OCP section of the datasheet.
Does the SIC467ED-T1-GE3 support pre-bias start-up, and how does it behave?
Yes, the SIC467ED-T1-GE3 supports pre-bias start-up. If the FB pin senses voltage above the internal soft-start ramp at power-on, the control logic disables both MOSFETs to prevent negative current flow through the low-side FET-avoiding output voltage collapse and excessive inrush into pre-charged loads.
What thermal protection features are integrated into the SIC467ED-T1-GE3?
The SIC467ED-T1-GE3 includes over-temperature protection (OTP) that disables both MOSFETs at 150 °C junction temperature, with 35 °C hysteresis (re-enabling at ~115 °C). OTP is automatically disabled during discontinuous conduction mode to avoid false trips at light loads-per functional description in Section 6 of the datasheet.
