Product details
Overview
VIPER013BLS from STMicroelectronics is a high-voltage offline PWM converter IC integrating an 800 V avalanche-rugged power MOSFET, current-mode PWM controller, and embedded HV startup circuit. It delivers 360 mA typical drain current limit, operates at 60 kHz ±7% jittered switching frequency, and supports self-supply operation to eliminate auxiliary winding components - enabling compact, low-noise flyback, buck, and buck-boost converters for sub-5 W AC/DC power supplies.
For engineers reviewing the VIPER013BLS datasheet, VIPER013BLS pinout, VIPER013BLS application, or VIPER013BLS equivalent, key selection criteria include its 800 V MOSFET breakdown rating, no-load input power <10 mW at 230 VAC, integrated thermal shutdown, and direct/secondary feedback compatibility in isolated and non-isolated topologies.
Technical Context
The VIPER013BLS implements a current-mode PWM control architecture with built-in oscillator jitter (±7% around 60 kHz) to reduce EMI filter cost, and pulse-frequency modulation (PFM) for ultra-low no-load consumption. Its integrated 800 V power MOSFET eliminates external HV startup resistors and enables direct rectified mains connection.
Control functions include embedded transconductance error amplifier (1.2 V reference), soft-start (8 ms typ.), overload protection with 200 ms max delay, and pulse-skip mode to prevent transformer flux runaway. The device supports both direct feedback (non-isolated) and optocoupler-based secondary feedback (isolated) via dedicated FB and COMP pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Drain voltage rating | 800 V - enables universal AC input (85–265 VAC) without snubber scaling penalties |
| Drain current limit | 360 mA typ. - sets maximum peak primary current for ~3.5 W output in flyback designs |
| Switching frequency | 60 kHz ±7% - jittered operation reduces conducted EMI peak amplitude and filter component count |
| No-load input power | <10 mW at 230 VAC - meets EU CoC Tier 2 and DOE Level VI standby efficiency requirements |
| VCC operating range | 4.5 V to 30 V - supports self-supply from auxiliary winding or external bias with wide dropout margin |
| Thermal shutdown | 160 °C typ. - protects against sustained overloads and poor heatsinking in enclosed adapters |
| FB reference voltage | 1.20 V ±25 mV - enables precise output regulation using standard resistor dividers in feedback networks |
Pinout & Package
The VIPER013BLS is housed in a thermally enhanced SSOP10 package with exposed drain pads (pins 6–10) for direct PCB copper pour heat sinking. Pin layout follows standardized SSOP10 mechanical outline (3.9 mm × 4.9 mm, 0.65 mm pitch), with GND (pin 1) and DRAIN (pins 6–10) assigned to minimize loop inductance in high-di/dt switching paths.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | MOSFET source & signal ground | Return path for internal sense-FET and bias currents; must be isolated from high-current return traces |
| 2 VCC | Controller supply rail | Charged by internal HV current source; requires local 0.1 µF bypass + bulk capacitor for stable operation |
| 3 DIS | Disable input | Triggers auto-restart OVP/OLP when voltage exceeds 1.2 V for >1 ms; tied to GND if unused |
| 4 FB | Inverting input of error amplifier | Accepts direct output voltage divider (non-isolated) or optocoupler signal (isolated); disables EA when shorted to GND |
| 5 COMP | Error amplifier output | Drives external compensation network; directly driven by optocoupler collector in secondary feedback mode |
| 6–10 DRAIN | Power MOSFET drain terminals | Internally connected to MOSFET die metal pad; require large copper pour for thermal dissipation and low RthJA |
Key Features
| Feature | Design Value |
|---|---|
| Self-supply capability | Eliminates auxiliary winding and bias components - reduces BOM count and board area in low-power SMPS |
| Jittered oscillator | ±7% frequency spread at 60 kHz - lowers EMI peak energy, enabling smaller/cheaper input filters |
| Pulse-frequency modulation (PFM) | Reduces switching activity under light load - achieves <10 mW no-load input power at 230 VAC |
| Integrated thermal shutdown | 160 °C trip threshold with hysteresis - prevents permanent damage during sustained overtemperature events |
| Direct and secondary feedback support | Configurable FB/COMP interface - enables both non-isolated (cost-sensitive) and isolated (safety-compliant) topologies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage offline converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VIPER012BLS | Lower 240 mA drain current limit; 120 kHz ±7% switching frequency | Better suited for higher-frequency, lower-power designs (<2 W) with tighter EMI bandwidth constraints | Select when optimizing for size over output power; not drop-in due to different FOSC and IDLIM |
| ICE2QS03G | 700 V MOSFET rating; external startup resistor required; no self-supply mode | Requires auxiliary winding for VCC; lacks integrated jitter and PFM for ultra-low standby | Choose only if legacy design reuse mandates Infineon footprint; higher BOM count and no-load power >35 mW |
Compared with VIPER013BLS, VIPER012BLS trades output power for higher switching frequency and reduced transformer size, while ICE2QS03G lacks integrated HV startup and self-supply - increasing component count and compromising no-load efficiency in modern energy standards.

FAQ
What is the maximum continuous output power achievable with VIPER013BLS in a flyback topology?
At 230 VAC input and 60 kHz operation, VIPER013BLS supports up to 3.5 W continuous output power in open-frame flyback designs with adequate PCB copper pour on DRAIN pins. This assumes 75% efficiency, 360 mA peak drain current limit, and proper thermal management limiting junction temperature to ≤125 °C per derating curves in the datasheet.
Can VIPER013BLS operate without an auxiliary winding?
Yes - VIPER013BLS supports self-supply mode where the internal HV current source charges the VCC capacitor directly from the DRAIN pin during startup and steady-state operation. This eliminates the need for an auxiliary winding, reducing transformer complexity and cost in low-power applications.
How does the DIS pin implement overvoltage protection?
The DIS pin triggers automatic restart protection when voltage exceeds 1.2 V for >1 ms. In non-isolated topologies, a resistor divider from rectified mains to DIS provides line OVP; in isolated designs, the same method applied to VCC enables output OVP. The 1 ms debounce prevents false triggering from noise transients.
Is VIPER013BLS compatible with primary-side regulation (PSR) schemes?
No - VIPER013BLS does not support true PSR. It requires either direct feedback (non-isolated) or optocoupler-coupled secondary feedback (isolated). PSR functionality demands integrated auxiliary winding sensing and digital compensation, which are absent in this analog current-mode controller.
