Product details
Overview
EVLVIP16H-4WFN from STMicroelectronics is a 115 kHz fixed-frequency off-line PWM controller with integrated 800 V avalanche-rugged power MOSFET, adjustable current limit (0.38–0.42 A), <30 mW standby power at 230 VAC, and on-board soft-start - designed for non-isolated flyback, buck, and buck-boost auxiliary power supplies in smart meters, LED drivers, and white goods.
For engineers reviewing the EVLVIP16H-4WFN datasheet, EVLVIP16H-4WFN pinout, EVLVIP16H-4WFN application, or EVLVIP16H-4WFN equivalent, key selection criteria include its self-biasing capability (no auxiliary winding required), burst-mode operation for ultra-low no-load consumption, 800 V drain withstand voltage, and thermal shutdown with 30 °C hysteresis.
Technical Context
The EVLVIP16H-4WFN implements a current-mode PWM controller with cycle-by-cycle overcurrent protection, an internal transconductance error amplifier (GM = 2 mA/V), and spread-spectrum frequency jittering (±8 kHz at 230 Hz) to reduce EMI. Its high-voltage start-up circuit draws current directly from the DRAIN pin above 40–60 V, enabling direct mains-derived operation.
It features dual-stage protection: hysteretic thermal shutdown (TSD = 150–160 °C) and automatic fault recovery via a digital up-down counter that disables switching after 50 ms overload and initiates soft-started restart after 1 s. The LIM pin allows resistor-programmable current limit down to 85 mA in burst mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching frequency | 115 kHz typical (VIPER16H type); ±8 kHz jitter at 230 Hz reduces EMI filter cost |
| Drain breakdown voltage | 800 V min; enables direct operation from 230 VAC rectified input without external HV MOSFET |
| Standby power | <30 mW at 230 VAC; meets Energy Star and EU CoC Tier 2 requirements |
| Current limit (IDlim) | 0.38–0.42 A typ at 25 °C; adjustable downward via external resistor on LIM pin |
| Soft-start time | 8.5 ms typ; prevents transformer saturation and secondary diode stress during startup |
| Burst-mode threshold | VCOMPL = 1.1 V typ; triggers low-power cycling when load drops below ~10% of full output |
| Thermal shutdown | 150–160 °C activation with 30 °C hysteresis; ensures safe derating under sustained overload |
Pinout & Package
Package: 4-pin WFN (4.0 mm × 4.0 mm, 0.75 mm height, exposed thermal pad). Designed for surface-mount assembly with bottom-side copper pour for thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Controller ground reference & MOSFET source connection | Common return for control logic, error amplifier, and power switch; must be low-inductance path to PCB ground plane |
| VDD | Control section supply input | Charged by internal HV generator; clamped at 23.5 V; powers internal logic and gate driver |
| LIM | Adjustable current limit set point | Sinks current to scale IDlim downward; open-circuit defaults to 0.4 A; capacitor ≤470 nF allowed for noise immunity |
| FB | Inverting input of transconductance error amplifier | Accepts feedback from output via single resistor (for VOUT = 3.3 V) or divider; internal 1 μA pull-up prevents floating |
| COMP | Error amplifier output & PWM comparator input | Drives external RC compensation network; also interfaces with optocoupler in isolated designs; linear range 1.1–3.0 V |
| DRAIN | High-voltage MOSFET drain terminal | Carries full primary current; connects to bulk capacitor; provides HV start-up current; thermally bonded to exposed pad |
Key Features
| Feature | Design Value |
|---|---|
| Self-biasing HV start-up | Draws charging current directly from DRAIN pin above 40–60 V; eliminates need for auxiliary winding or bias circuit |
| Programmable overcurrent protection | LIM pin allows resistor-based reduction of peak drain current limit from 0.4 A down to 85 mA in burst mode |
| Hysteretic thermal shutdown | Shuts down at 150–160 °C and remains off until junction cools by ≥30 °C - prevents thermal runaway in enclosed adapters |
| Burst-mode operation | Reduces average switching frequency to hundreds of Hz under light load, cutting core loss, conduction loss, and audible noise |
| Open-loop failure protection | Detects FB pin disconnection or feedback loss and forces shutdown within 100 ms to prevent unregulated overvoltage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar off-line SMPS controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICE2QS03G | 700 V MOSFET, 65 kHz fixed frequency, no LIM pin adjustment, higher standby power (~60 mW) | Lacks programmable current limit and burst-mode depth; requires auxiliary winding for VDD | Prefer when lower BOM cost outweighs efficiency and design flexibility needs |
| LNK306P | 700 V MOSFET, 66 kHz, integrated X-cap discharge, no soft-start, 132 mW standby at 230 VAC | No thermal hysteresis, no auto-restart timer, limited compensation flexibility on FB/COMP | Choose only for cost-sensitive, non-regulated auxiliary rails where safety certification is pre-validated |
Compared with ICE2QS03G and LNK306P, EVLVIP16H-4WFN delivers superior light-load efficiency (<30 mW), precise current limiting via LIM pin, and robust fault recovery - making it optimal for space-constrained, thermally demanding, and energy-compliant auxiliary supplies.

FAQ
What is the maximum continuous output power achievable with EVLVIP16H-4WFN in an open-frame design?
At 50 °C ambient with adequate heat sinking, EVLVIP16H-4WFN delivers up to 6 W continuously in open-frame configurations. This rating assumes proper PCB copper area under the DRAIN pad (≥100 mm²), SO16N package, and optimized layout per ST's AN4170 guidelines. Derating applies above 50 °C ambient.
Can EVLVIP16H-4WFN operate without an external feedback optocoupler in isolated topologies?
No - in isolated flyback designs, the internal error amplifier must be disabled (FB pin shorted to GND), and regulation relies entirely on an external optocoupler feeding current into the COMP pin. The device does not support primary-side sensing or auxiliary winding feedback for isolation.
How is the 800 V drain rating utilized in practical 230 VAC designs?
The 800 V rating accommodates worst-case transient overvoltages (e.g., 230 VAC × √2 ≈ 325 V + 400 V surge = 725 V), ensuring margin against lightning-induced spikes and transformer leakage inductance kickback. It eliminates need for external snubbers in most Class II insulated designs.
Does the LIM pin support dynamic current limiting during transient load steps?
No - the LIM pin sets a static, resistor-defined current limit threshold before startup. During operation, the limit is fixed unless the external RLIM resistor value changes. Transient overcurrent response is handled by the fixed-cycle OCP comparator, which reacts within one switching cycle (≤8.7 µs at 115 kHz).
