Product details
Overview
SiP12107DMP-T1-GE3 from Vishay Siliconix is a 5 V input, 3 A current-mode constant-on-time (CM-COT) synchronous buck regulator with integrated high-side and low-side MOSFETs in a 3 mm × 3 mm QFN16-33G package. It delivers adjustable output down to 0.6 V from 2.8–5.5 V input, achieves 95 % peak efficiency at 2 MHz, and supports all-ceramic output capacitors without external ESR networks - ideal for point-of-load regulation in notebook computers and telecom POL applications.
For engineers reviewing the SiP12107DMP-T1-GE3 datasheet, SiP12107DMP-T1-GE3 pinout, SiP12107DMP-T1-GE3 application, or SiP12107DMP-T1-GE3 equivalent, this page provides verified technical context on its CM-COT control architecture, ultrafast transient response, power-saving mode operation, and full protection set including OVP/UVP/OTP/PGOOD - critical for stable, compact DC/DC designs in space-constrained computing and industrial systems.
Technical Context
The SiP12107DMP-T1-GE3 implements a current-mode constant-on-time (CM-COT) control scheme using internal valley-current sensing and a programmable RON resistor to set on-time. Its error amplifier transconductance is 1 mS, reference voltage is 0.600 V ±0.009 V over –40 °C to +85 °C, and minimum on-time is 50 ns - enabling stable operation up to 4 MHz switching frequency with minimal output capacitance.
It integrates a ~56 mΩ high-side p-channel MOSFET and ~33 mΩ low-side n-channel MOSFET, supports diode emulation and frequency foldback in power-saving mode, and features dedicated pins for loop compensation (GMO), soft-start ramping (internal 1.5 ms), and pre-bias startup protection - ensuring monotonic VOUT rise and no negative voltage spikes during hot-plug conditions.

Pinout & Package
SiP12107DMP-T1-GE3 is housed in a lead-free, power-enhanced QFN16-33G package (3 mm × 3 mm, 0.5 mm pitch, exposed thermal pad). The package supports high thermal conductivity to PCB and accommodates 3 A continuous current with ≤36.3 °C/W junction-to-ambient thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pins 1, 16) | Power input for high-side MOSFET | Dual-pin connection reduces IR drop and improves current sharing for 3 A load; accepts 2.8–5.5 V with –0.3 V to 6 V absolute max rating. |
| AVIN (Pin 2) | Bias supply for internal control circuitry | Separate analog rail enables independent noise isolation; UVLO threshold is 2.55 V with 300 mV hysteresis. |
| EN (Pin 3) | Enable control input | Logic-high threshold ≥1.5 V; enables precise power sequencing with external pull-up or microcontroller GPIO. |
| RON (Pin 4) | On-time programming resistor terminal | Connects to GND via resistor (e.g., 105 kΩ for 1 MHz); sets fixed on-time per cycle in CM-COT architecture. |
| AUTO (Pin 5) | Power-saving mode selector | Connect to GND for diode-emulation + frequency foldback; connect to AVIN/VIN for forced PWM across full load range. |
| PGD (Pin 6) | Open-drain power-good indicator | Asserts high when VFB is within ±10 % of 0.6 V; requires external 10 kΩ pull-up to monitor output regulation status. |
| GMO (Pin 7) | Compensation and droop network node | Connects external RC network (e.g., 4 kΩ + 1 nF) to AGND for type-II loop compensation and load-line droop tuning. |
| AGND (Pin 8) | Analog ground reference | Separate ground for feedback and control circuitry; must be star-connected to PGND under thermal pad to minimize noise coupling. |
| VFB (Pin 9) | Feedback input referenced to 0.6 V | High-impedance (2–200 nA bias) node; senses output via resistive divider to set VOUT = 0.6 × (1 + R1/R2). |
| VOUT (Pin 10) | Output voltage sense point | Direct connection to regulated rail; used for remote sensing to compensate PCB trace IR drop in high-current POLs. |
| LX (Pins 11–13) | Switch node / inductor connection | Three parallel pins reduce parasitic inductance and thermal resistance; rated for –0.3 V to 5.5 V with 50 ns min on-time capability. |
| PGND (Pins 14–15) | Power ground return path | Dual thermal pads provide low-inductance return for high di/dt switching currents; must be solidly connected to exposed die paddle. |
Key Features
| Feature | Design Value |
|---|---|
| Current-mode COT control | Delivers <100 ns load-step response with no external ESR network required - eliminates bulk electrolytic capacitors and simplifies layout. |
| Integrated power MOSFETs | 56 mΩ high-side p-MOS + 33 mΩ low-side n-MOS enable 95 % efficiency at 2 MHz - reduces BOM count and PCB area vs. controller+discrete-FET solutions. |
| Selectably optimized light-load efficiency | Diode emulation + frequency foldback in PSM cuts quiescent current to <1 mA at 10 mA load - extends battery life in always-on subsystems. |
| Full fault protection suite | OVP/UVP latching, pulse-by-pulse OCP, and thermal shutdown with 35 °C hysteresis ensure safe operation during short circuits, cold starts, and thermal overload. |
| Pre-bias startup support | Monitors VFB during startup; disables switching if output voltage exceeds internal ramp - prevents reverse current and output collapse in hot-swap applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS543320RTWR | 4 A output, 2.2 V–18 V input, 1.5 MHz fixed frequency, requires external compensation; no PSM mode. | Better suited for higher-input industrial rails; lacks automatic light-load optimization and pre-bias startup. | Choose TPS543320RTWR only when input exceeds 5.5 V or 4 A output is required - not a drop-in replacement due to different pinout and control architecture. |
| MP2332HG-LL-Z | 3 A output, 4.5–21 V input, 500 kHz–2.2 MHz adjustable frequency, proprietary adaptive COT, no GMO pin for droop tuning. | Targeted at wider-input industrial applications; lacks dedicated VOUT sense pin and PGOOD hysteresis window specification. | MP2332HG-LL-Z fits where input >5.5 V is needed and droop control is unnecessary - but requires redesign of compensation and feedback network. |
Compared with TPS543320RTWR and MP2332HG-LL-Z, SiP12107DMP-T1-GE3 offers superior light-load efficiency via configurable PSM, tighter reference accuracy (±1 % vs. ±1.5 %), and integrated VOUT sense for remote regulation - making it optimal for space-constrained, battery-sensitive, and high-precision POL applications below 5.5 V input.

FAQ
What is the maximum switching frequency supported by SiP12107DMP-T1-GE3?
SiP12107DMP-T1-GE3 supports a programmable switching frequency up to 4 MHz, set by the external RON resistor connected between Pin 4 and GND. At 4 MHz, the device maintains stable regulation with ultra-low output ripple and enables use of sub-1 μH inductors. The minimum on-time is guaranteed at 50 ns, and frequency variation remains within specification across load and input voltage ranges per the CM-COT architecture.
Does SiP12107DMP-T1-GE3 require external ESR for loop stability?
No, SiP12107DMP-T1-GE3 does not require external ESR or an ESR network for loop stability. Its current-mode COT control architecture uses internal valley-current sensing to achieve inherent stability with all-ceramic output capacitors. A simple RC network (type-II compensator) between GMO (Pin 7) and AGND (Pin 8) is sufficient for transient optimization - eliminating the need for bulk tantalum or aluminum electrolytic capacitors.
How does the AUTO pin affect SiP12107DMP-T1-GE3 operation?
The AUTO pin (Pin 5) selects between power-saving mode (PSM) and forced PWM operation. When tied to GND, SiP12107DMP-T1-GE3 enters PSM - enabling diode emulation and frequency foldback to maximize light-load efficiency. When tied to AVIN or VIN, it forces continuous PWM mode across the full 0–3 A load range, ensuring fixed-frequency operation and predictable EMI behavior for noise-sensitive applications.
What protection features are integrated into SiP12107DMP-T1-GE3?
SiP12107DMP-T1-GE3 integrates output overvoltage protection (OVP, +20 %), output undervoltage protection (UVP, –25 %), overtemperature protection (OTP, 160 °C with 35 °C hysteresis), pulse-by-pulse overcurrent protection (OCP, 4.5 A typical), and input UVLO (2.55 V with 300 mV hysteresis). All protections are active after AVIN exits UVLO, and UVP latches off the device until EN or AVIN is cycled.
Can SiP12107DMP-T1-GE3 support pre-bias startup?
Yes, SiP12107DMP-T1-GE3 supports pre-bias startup. During initial power-up, it monitors the VFB pin; if the sensed voltage exceeds the internal reference ramp value, the control logic disables both high-side and low-side MOSFETs to prevent reverse current flow and negative output voltage spikes - essential for hot-swap and redundant power supply applications.
