1 Features
• Functional Safety-Capable
– Documentation available to aid functional safety
system design
• 4.5-V to 42-V wide input voltage range
• Extended power range from less than 1 W to more
than 50 W
• Robust PSR flyback design for reliable and rugged
applications
– Robust design with only a transformer crossing
the isolation barrier
– ±1.5 total output regulation accuracy
– Optional VOUT temperature compensation
– Input UVLO and thermal shutdown protection
– Hiccup-mode overcurrent fault protection
– 0.9-mm HV-LV pin spacing in 14-pin HTSSOP
package
– –40°C to +150°C junction temperature range
• Integration reduces design size and cost
– No optocoupler or transformer auxiliary winding
required for VOUT regulation
– 2-A peak sink and 1-A peak source high-current
power MOSFET gate driver
• High efficiency with best-in-class active IQ
– Quasi-resonant switching in boundary
conduction mode (BCM) at heavy load
– External VCC option for improved efficiency
– High light-load efficiency with lowest IQ (25-μA
typical with external VCC)
– Single and multiple output implementations
• Ultra-low conducted and radiated EMI signatures
– Soft switching avoids diode reverse recovery
– Designed for CISPR 32 EMI requirement
• Create a custom design using LM25185 with
WEBENCH® Power Designer
2 Applications
• Factory automation and control: Isolated field
transmitters, field actuators, and multiple output
rails for analog input modules
• Motor drives: IGBT and SiC gate drive supplies
• Solar energy systems: Micro inverter and Solar
power optimizer
• PoE PD DC/DC converters
• Building automation HVAC systems
• Generic isolated bias power rails for industrial and
telecom systems
• Generic IGBT, MOSFET, GaN and SiC gate drivers
3 Description
The LM25185 is a primary-side regulated (PSR)
flyback controller with high efficiency over a wide
input voltage range of 4.5 V to 42 V. The
isolated output voltage is sampled from the primaryside
flyback voltage, eliminating the need for an
optocoupler, voltage reference, or third winding from
the transformer for output voltage regulation.
