PI Expert Suite design software
Power Integration’s PI Expert Suite Version 8.5 is a piece of power supply design productivity software that is compatible with the company’s HiperLCS range of high-frequency LLC converter ICs and its TOPSwitch-JX series of integrated offline switcher ICs.
The software can simplify design processes by producing a complete schematic of the power supply and features a power transformer design and a wide range of materials.
The latest version also includes thermal calculations for improved heatsink performance and provides PCB layout recommendations for the selected device and package type.
Additionally, an updated library of components includes fuses, fusible resistors, shunt regulators, optocouplers, and heatsinks.
Key product features
- Available in 32-bit and 64-bit versions
- 64-bit version features a larger system memory and faster processor speeds
- The suite is available in English, traditional Chinese, Simplified Chinese, Korean, Japanese, and Russian languages
- Transformer prototypes resulting from the use of this software can be ordered through Power Integrations’ Rapid Transformer Sample Service
Power Integrations has launched its Linkswitch-3 series of integrated monolithic switching ICs. The devices are claimed to deliver accurate primary-side regulation for chargers and adapters up to 10W, making them suitable for smartphones, tablets and other mobile devices, particularly those subject to 30mW no-load limitations, such as upcoming mandatory US DoE EPS efficiency regulations and EU CoC Tier 2 guidelines.
This document from Power Integrations is an engineering report describing a non-isolated LED driver (power supply) utilising a LNK458KG from the Linkswitch-PL series of devices.
The Linkswitch-PH has been developed to cost-effectively design a single-stage power-factor-corrected LED driver with primary-side constant-current control.
This design idea presents the schematic for a CV/CC power supply for LED driver applications using the Linkswitch-II LNK605DG.
The power supply shown in this design idea uses a Linkswitch-TN device in a boost converter configuration to deliver a constant current of 20mA from a single positive voltage of 554VDC.
