STMicroelectronics EVLVIP16H-4WFL

Overview

EVLVIP16H-4WFL from STMicroelectronics is a fixed-frequency off-line PWM controller with integrated 800 V avalanche-rugged power MOSFET, designed for non-isolated and isolated flyback/ buck-buck-boost converters in auxiliary power supplies. It delivers up to 10 W in open-frame designs at 50 °C ambient, operates at 115 kHz (±8 kHz jitter), supports <30 mW standby power at 230 VAC, and features adjustable overcurrent limit via external resistor on LIM pin.

For engineers reviewing the EVLVIP16H-4WFL datasheet, EVLVIP16H-4WFL pinout, EVLVIP16H-4WFL application, or EVLVIP16H-4WFL equivalent, this device serves as a self-biasing, low-EMI AC-DC converter IC eliminating auxiliary windings - critical for compact, energy-compliant auxiliary supplies in appliances, power meters, and LED drivers.

Technical Context

The EVLVIP16H-4WFL integrates an 800 V power MOSFET with 20 Ω typical R_DS(on) at 25 °C and 40–48 Ω at 125 °C, enabling direct mains rectified input operation without auxiliary bias. Its current-mode PWM controller uses cycle-by-cycle drain current sensing via SenseFET architecture and features internal soft-start (8.5 ms) and hysteretic thermal shutdown (150–160 °C).

It implements spread-spectrum frequency jittering (±4 kHz @ 60 kHz / ±8 kHz @ 115 kHz at 230 Hz) to reduce EMI filter cost, burst-mode operation (V_COMPL = 1.1 V, hysteresis 40 mV) for <30 mW standby compliance, and open-loop failure protection triggered by COMP pin current threshold (4 mA).

Key Specifications

Pinout & Package

EVLVIP16H-4WFL is housed in SO16 narrow (SO-16N) package with exposed DRAIN pins (7,8,13–16) thermally connected to the metal frame for enhanced heat dissipation. The package complies with JEDEC MS-012AC and supports standard FR4 PCB layout with ≥100 mm² copper pour under DRAIN pins.

FAQ

What is the maximum continuous output power achievable with EVLVIP16H-4WFL in an open-frame design?

EVLVIP16H-4WFL delivers up to 10 W continuous output power in open-frame configurations at 50 °C ambient temperature with adequate heat sinking, as verified in ST's DocID15232 Rev 7, Table 2. This assumes SO16N package mounted on standard FR4 with ≥100 mm² copper pour under DRAIN pins and proper layout per Section 16.

Does EVLVIP16H-4WFL require an auxiliary winding for VDD biasing?

No. EVLVIP16H-4WFL incorporates an internal high-voltage current generator that draws charging current directly from the DRAIN pin, enabling self-biasing without auxiliary winding. This feature is confirmed in Sections 7 and 8 of the datasheet and reduces transformer complexity and cost in both isolated and non-isolated topologies.

How is overcurrent protection adjusted on EVLVIP16H-4WFL?

Overcurrent protection is adjusted using an external resistor (R_LIM) between the LIM pin (Pin 6) and GND. As shown in Figure 13 and Table 8, sinking current from LIM scales ID_lim downward from its default 0.4 A value. Leaving LIM open retains the default limit; R_LIM > 80 kΩ has negligible effect.

What thermal protection mechanism does EVLVIP16H-4WFL implement?

EVLVIP16H-4WFL features hysteretic thermal shutdown with trip at 150–160 °C and 30 °C hysteresis (T_SD and T_HYST in Table 8). When junction temperature exceeds the upper threshold, the power MOSFET is disabled; it remains off until temperature falls below (T_SD − T_HYST), then resumes operation with soft-start - preventing thermal cycling damage.
