Product details
Overview
VIPER013XS from STMicroelectronics is a high-voltage off-line SMPS controller integrating an 800 V avalanche-rugged N-channel power MOSFET, current-mode PWM control, and embedded HV startup circuitry. It delivers up to 4.5 W in open-frame designs at 230 VAC, supports 120 kHz ±7% jittered switching, and achieves <10 mW no-load input power at 230 VAC - enabling compliance with stringent energy-saving standards in low-power flyback, buck, and buck-boost converters for home appliances and lighting.
For engineers reviewing the VIPER013XS datasheet, VIPER013XS pinout, VIPER013XS application, or VIPER013XS equivalent, this device is selected for ultra-wide AC input (85–265 VAC) offline power supplies requiring minimal external components, self-supply capability without auxiliary winding, and integrated OCP/OLP/VCC clamp/thermal shutdown protections.
Technical Context
The VIPER013XS implements a fixed-frequency current-mode PWM controller with built-in jitter (±7% around 120 kHz) to reduce EMI filter cost, and features a dedicated sense-FET for lossless peak current detection. Its internal 800 V start-up FET and switchable HV current source enable direct DRAIN-connected startup without external bias circuitry.
It integrates a transconductance error amplifier referenced to 1.2 V, soft-start (8 ms), pulse-skipping for light-load PFM operation, and automatic-restart protections including overload (tOVL_MAX = 400 ms), line/output OVP, and thermal shutdown at 150 °C. The DIS pin enables programmable input/output overvoltage protection via external voltage divider.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching frequency | 120 kHz ±7% - jittered spread-spectrum operation reduces peak EMI and enables smaller input EMI filters. |
| Drain breakdown voltage | 800 V - supports universal AC input (85–265 VAC) and reduces snubber size/cost in flyback designs. |
| Max. drain current (peak) | 360 mA typ. at 25 °C - sets output power limit (~4.5 W open-frame at 230 VAC). |
| VCC operating range | 4.5 V to 30 V - enables flexible supply options: self-supply (no auxiliary winding) or external bias. |
| No-load input power | <10 mW @ 230 VAC - meets EU CoC Tier 2 and DOE Level VI standby efficiency requirements. |
| Thermal shutdown threshold | 150 °C - protects MOSFET and IC under sustained overload or poor heatsinking conditions. |
| Soft-start time | 8 ms - prevents inrush current and flux runaway during startup and fault recovery. |
| OCP trip level | 360 mA typ. (VIPER013X variant) - cycle-by-cycle current limiting with adjustable threshold via COMP pin. |
Pinout & Package
Package: SSOP10 (3.9 mm × 4.9 mm, 0.65 mm pitch), thermally enhanced with DRAIN pins (6–10) connected to internal MOSFET metal pad for PCB copper-area heat sinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Ground reference & MOSFET source | Return path for bias currents and internal MOSFET source; must be isolated from pulsed return paths to minimize noise coupling. |
| 2 VCC | Controller supply rail | Charged by internal HV current source at startup; powers internal logic; requires ≥10 µF storage + 0.1 µF ceramic bypass. |
| 3 DIS | Disable input | Triggers auto-restart OVP if voltage exceeds 1.2 V for >1 ms; used for line or output overvoltage protection. |
| 4 FB | Inverting input of error amplifier | Receives feedback voltage referenced to 1.2 V internal reference; shorting to GND disables regulation. |
| 5 COMP | Error amplifier output | Drives peak current setpoint; compensation network between COMP and GND stabilizes control loop. |
| 6–10 DRAIN | MOSFET drain terminals | High-voltage switching node; internally connected to 800 V MOSFET drain; requires large PCB copper pour for thermal dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 800 V avalanche-rugged MOSFET | Eliminates need for external HV switch and reduces BOM count in sub-5 W offline SMPS. |
| Self-supply operation | Removes auxiliary winding and associated diode/capacitor, simplifying transformer design and reducing cost. |
| Jittered 120 kHz oscillator | Spreads EMI spectrum to lower peak emissions, enabling smaller/cheaper EMI input filters. |
| Pulse-skip light-load mode | Reduces switching losses at light loads, achieving <10 mW no-load consumption for energy standard compliance. |
| Embedded thermal shutdown & OCP/OLP | Single-chip protection suite with automatic restart avoids external protection ICs and discrete sensing. |
Applications
| Smart Home Lighting Control | Low-Power Appliance Power Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage offline SMPS controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICE2QS03G | 650 V MOSFET, fixed 65 kHz, no jitter, requires external startup resistor and bias supply. | Lacks self-supply and integrated HV startup; higher component count and noisier EMI profile. | Choose when legacy design reuse or lower-cost MOSFET voltage rating suffices and jitter is not required. |
| LNK3206P | 725 V MOSFET, 66 kHz, integrated X-cap discharge, but no DIS pin or programmable OVP. | Supports auto-restart OLP only; lacks dedicated disable input for custom OVP implementation. | Prefer for designs needing integrated X-cap safety discharge but not requiring DIS-based protection flexibility. |
Compared with VIPER013XS, ICE2QS03G requires external startup and bias components, increasing BOM and layout complexity, while LNK3206P omits the DIS pin - limiting overvoltage protection configurability - and offers no jittered switching for EMI reduction.

FAQ
What is the maximum continuous output power achievable with VIPER013XS?
VIPER013XS delivers up to 4.5 W in open-frame configurations at 230 VAC ambient temperature of 50 °C with adequate PCB copper heatsinking. In enclosed non-ventilated adapters, typical continuous output is limited to 7 W at 50 °C ambient, constrained by thermal resistance (RTH-JA = 95 °C/W with 100 mm² Cu) and internal 150 °C thermal shutdown threshold.
Can VIPER013XS operate without an auxiliary winding?
Yes - VIPER013XS supports self-supply mode where the internal HV current source recharges the VCC capacitor during MOSFET OFF time, eliminating the need for an auxiliary winding, bias diode, and capacitor. This is enabled by connecting only a single VCC storage capacitor (≥10 µF) and relying on ICH3 (7.6–10 mA) for steady-state supply.
How does the DIS pin implement overvoltage protection?
The DIS pin triggers auto-restart protection when voltage exceeds 1.2 V for more than 1 ms. For input OVP, a resistor divider from rectified mains to DIS sets the trip point; for output OVP in non-isolated topologies, the same divider connects from output to DIS. If unused, DIS must be tied to GND to disable the function.
What is the purpose of jittered switching in VIPER013XS?
Jitter modulates the 120 kHz switching frequency by ±7% at 260 Hz to spread harmonic energy across a bandwidth, lowering peak conducted EMI amplitude. This allows use of smaller, lower-cost input EMI filters - particularly beneficial for average-detected EMI compliance testing per CISPR 22/32.
