Product details

Overview

EVLVIP16L-4WFL from STMicroelectronics is a fixed-frequency, off-line AC-DC converter IC integrating an 800 V avalanche-rugged power MOSFET, PWM controller, adjustable overcurrent limit, hysteretic thermal shutdown, and on-board soft-start. It delivers up to 10 W in open-frame designs at 50 °C ambient, operates at 60 kHz with ±4 kHz frequency jittering for EMI reduction, and achieves <30 mW standby power at 230 VAC - enabling capacitive supply replacement in auxiliary power supplies for smart meters and LED drivers.

For engineers reviewing the EVLVIP16L-4WFL datasheet, EVLVIP16L-4WFL pinout, EVLVIP16L-4WFL application, or EVLVIP16L-4WFL equivalent, this device is selected for low-component-count, self-biased flyback/buck-boost converters requiring high-voltage ruggedness, burst-mode efficiency compliance (e.g., Energy Star Level VI), and integrated fault recovery without auxiliary winding.

Technical Context

The EVLVIP16L-4WFL implements a current-mode PWM architecture with cycle-by-cycle drain current sensing via internal SenseFET, where the COMP pin voltage directly modulates peak current limit against a reference derived from FB. Its oscillator uses fixed 60 kHz center frequency with 230 Hz spread-spectrum modulation (±4 kHz) to suppress harmonic peaks.

Power delivery relies on high-voltage startup from DRAIN (40–60 V threshold), followed by self-supply via internal HV current generator during MOSFET off-time; VDD regulation (11.5–23.5 V) enables operation without auxiliary winding. Protection includes auto-restart after overload (50 ms timeout, 1 s restart delay), open-loop failure detection, and thermal shutdown at 150–160 °C with 30 °C hysteresis.

Key Specifications

Parameter	Value and Actual Design Meaning
Operating Frequency	60 kHz ±4 kHz - fixed center with jittering reduces EMI filter cost and simplifies compliance testing.
Drain Voltage Rating	800 V - enables direct rectified mains connection (85–265 VAC) without external HV MOSFET or snubber.
Standby Power	<30 mW at 230 VAC - meets strict no-load energy regulations (e.g., EU CoC Tier 2, DOE Level VI).
Current Limit	0.4 A typical (adjustable via LIM pin resistor) - sets primary-side OCP threshold for transformer and diode stress control.
Soft-Start Time	8.5 ms - limits inrush current and prevents transformer saturation during cold start or fault recovery.
Burst Mode Threshold	VCOMP ≤ 1.1 V (with 40 mV hysteresis) - triggers ultra-low-power mode to maintain regulation under light loads.
Thermal Shutdown	150–160 °C with 30 °C hysteresis - ensures safe derating and automatic recovery without external thermal sensor.

Pinout & Package

Package: SO16 narrow (16-pin, 0.150" wide body, exposed thermal pad). Pin layout optimized for heat dissipation: DRAIN pins (13–16) are internally connected to metal frame and require copper pour beneath for thermal management.

Pin/Terminal	Circuit Role	Design Meaning
GND (Pins 1–2)	Controller ground reference	Source node for internal MOSFET and error amplifier - must be low-impedance connection to PCB ground plane.
VDD (Pin 5)	Control section supply	Charges external capacitor; clamped at 23.5 V - powers logic, gate driver, and protection circuits.
LIM (Pin 6)	Adjustable current limit input	Sinks current to reduce default 0.4 A OCP threshold; open-circuit = full rating; resistor sets precise trip point.
FB (Pin 7)	Inverting error amplifier input	Accepts feedback voltage; internal 3.3 V reference enables single-resistor output sensing (non-isolated) or opto-coupler interface (isolated).
COMP (Pin 8)	Error amplifier output	Drives RC compensation network; linear range 1.1–3.0 V - used for loop stability and opto-transistor control in isolated topologies.
DRAIN (Pins 13–16)	High-voltage power switch drain	Carries full primary current and HV startup current; thermally bonded to package frame - requires dedicated copper area for heatsinking.

Key Features

Feature	Design Value
No auxiliary winding required	Internal HV current generator draws startup and operating bias directly from DRAIN - eliminates transformer auxiliary winding and associated rectifier/capacitor.
Frequency jittering	±4 kHz modulation at 230 Hz spreads switching energy across spectrum - reduces peak EMI by >10 dB and eases EN55022 Class B filtering.
Safe auto-restart	Integrated up-down counter disables switching after 50 ms overload, then initiates soft-start after 1 s - prevents thermal runaway while maintaining system availability.
Hysteretic thermal protection	Shuts down at 150–160 °C junction temperature and re-enables only after 30 °C cooldown - avoids oscillatory tripping near thermal limit.
Burst mode operation	Reduces average switching frequency to hundreds of Hz under light load - cuts core loss, conduction loss, and audible noise while sustaining regulation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar off-line AC-DC converter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
VIPER22ADIP	Higher 22 W output capability, 730 V MOSFET, 60 kHz fixed frequency, but no frequency jittering or burst mode.	Targeted at higher-power adapters; lacks EMI-reduction features critical for compact enclosed designs.	Select when >10 W continuous output is needed and EMI filtering budget allows larger components.
ICE3B0565J	Fixed 65 kHz frequency, 650 V MOSFET, integrated X-cap discharge, but requires auxiliary winding and has higher standby power (~100 mW).	Designed for cost-sensitive consumer adapters; not suitable for ultra-low-standby or auxiliary-winding-free designs.	Choose for legacy designs where auxiliary winding exists and EMI requirements are less stringent.

Compared with VIPER22ADIP and ICE3B0565J, EVLVIP16L-4WFL uniquely combines 800 V ruggedness, jittering, burst mode, and zero-auxiliary-winding operation - making it optimal for space- and efficiency-constrained auxiliary supplies where reliability under transient stress is critical.

FAQ

What is the maximum continuous output power of EVLVIP16L-4WFL in an open-frame design?

EVLVIP16L-4WFL delivers up to 10 W continuous output power in open-frame configurations at 50 °C ambient temperature with adequate heat sinking, as confirmed in Table 2 of the official datasheet (DocID15232 Rev 7). This assumes proper PCB copper area under DRAIN pins and standard FR4 layout per Section 16 guidelines.

Can EVLVIP16L-4WFL operate without an auxiliary winding?

Yes - EVLVIP16L-4WFL integrates a high-voltage current generator that draws startup and operating bias directly from the DRAIN pin, eliminating the need for an auxiliary winding. This is validated in Sections 7 and 8 of the datasheet, where self-supply operation is described for both startup and steady-state conditions.

How does the LIM pin adjust overcurrent protection?

The LIM pin sinks current to lower the default 0.4 A drain current limit. Connecting a resistor RLIM between LIM and GND sets the sunk current, which linearly reduces IDlim per Figure 13 and Section 11. Leaving LIM open retains the full 0.4 A rating; RLIM >80 kΩ yields negligible adjustment.

What thermal protection mechanism does EVLVIP16L-4WFL use?

EVLVIP16L-4WFL employs a hysteretic thermal shutdown with activation at 150–160 °C junction temperature and 30 °C hysteresis (Section 4.1, Table 4). When triggered, the power MOSFET is disabled until junction temperature drops below ~120–130 °C, preventing oscillatory tripping during sustained thermal stress.
