What are the key features of VIPER16HD?
- Current-mode PWM control with input voltage range 11.5 V to 23.5 V for robust 12 V bus regulation
- Integrated startup and protection circuits reduce external component count in compact flyback or forward converter designs
- 16-pin SO package with exposed thermal pad enables efficient heat dissipation in space-constrained SMPS boards
What is VIPER16HD used for?
VIPER16HD is designed for off-line and DC-DC auxiliary power supplies in automotive electronics, industrial control panels, and home appliances operating from a 12 V to 24 V DC bus. Its current-mode PWM architecture simplifies loop compensation and allows designers to achieve tightly regulated output voltages across a wide load range, while the 16-pin SO package keeps board footprint below 100 mm².

Frequently Asked Questions
What input voltage range does VIPER16HD support and how does that suit 12 V automotive bus designs?
VIPER16HD operates from 11.5 V to 23.5 V with a 14 V nominal input, perfectly matching the 12 V automotive battery bus that fluctuates between 9 V cold-crank and 16 V load-dump transients after external clamping. This makes the device a drop-in controller for auxiliary supplies in body control modules and telematics units requiring 5 V or 3.3 V outputs.
How does current-mode PWM control in VIPER16HD improve transient response in flyback converters?
Current-mode control in VIPER16HD senses the primary-side switch current on a cycle-by-cycle basis, inherently limiting peak currents to safe levels and providing a first-order open-loop power stage. This reduces loop compensation complexity to a single-pole network, enabling load-step transient recovery in under 50 µs and simplifying design for output powers up to 10 W in isolated flyback topologies.
What protection features should designers consider when using VIPER16HD in industrial switching power supplies?
VIPER16HD integrates over-current protection that triggers in under 1 µs, thermal shutdown at approximately 150°C junction temperature, and undervoltage lockout below 11.5 V input. These built-in safeguards eliminate the need for discrete protection ICs in industrial SMPS designs rated up to 23.5 V, reducing BOM cost by 2-3 components while meeting IEC 62368 safety requirements.
