Enabling Predictable SuccessPower Integrations’ highly integrated ICs enable the design and production of switch-mode power supplies that use up to 70% fewer components compared to discrete solutions. Switchers that incorporate our ICs are smaller, lighter, and more portable than comparablepower supplies.

We combine a high-voltage power MOSFET switch with a controller on a single chip to provide key power supply functions, such as:

• High-voltage start-up• Short-circuit and open-loop protection• Programmable current limit• Line undervoltage and overvoltage protection• Output overvoltage protection• Accurate over-temperature and over-power protection• Soft-start• Feedback compensation• Remote ON/OFF

Design Simplification

LinkSwitch-PH and LYTSwitch dramatically simplify isolated flyback LED driver designs by eliminating an optocoupler and secondary control circuitry. The devices introduce a revolutionary control technique to provide very tight output regulation, compensating for transformer and internal parameter tolerances, along with input voltage variations. In addition the switching stage combines PFC + CC control functions, greatly reducing component count and increasing efficiency.

Achieves Less Than 10% THD with LYTSwitch-4 and LinkSwitch-PH Designs

Design Simplification

Low THD design (<10% THD) can easily be achieved with the LinkSwitch-PH and LYTSwitch-4 product families.

In order to achieve very low THD a simple line feed-forward circuit (shown below as RF and CF) can be added to bias the feed-forward circuit on the control stage. Contact your local PI representative for more information.

Product Features & Benefits

Line Overvoltage ProtectionPower Integration’s protection features include line overvoltage protection. Input voltage is monitored continuously by the IC. In the event that line voltage exceeds a safe operating point, switching is disabled. When line voltage returns to a safe level, switching restarts.

By interrupting switching, output reflected voltage (VOR) is removed as a cause of stress on the switching stage. This together with the 700 V power MOSFET in the PI IC ensures a high level of protection against input surges and line swells.

A small amount of hysteresis is built into the OVP function to present misfiring. This is important in environments where high-line impedance is encountered.

Notes: 1. Typical output current in a non-isolated buck converter. See Key

Applications Considerations section in data sheet for more information.

2. MDCM – mostly discontinuous mode.3. CCM – continuous conduction mode.4. PF high: >0.7 @ 120 VAC and >0.5 @ 230 VAC. 5. PF low: for non-PF application where CIN >5 µF minimum.6. Packages: P: PDIP-8B, D: SO-8C.

Additional Features:• High power factor meeting EU and USA requirements• Very low component count• Frequency jitter reduces EMI• No bias winding or transformer required

LYTSwitch-3 – Single-Stage LED Driver IC with Combined PFC and Constant Current Output for Outstanding TRIAC Dimming in Isolated and Non-Isolated Topologies

Notes: 1. Maximum practical continuous power in an open frame design

with adequate heat sinking, measured at 50˚C ambient (see Key Applications Considerations for more information).

2. ”x” digit describes VDSON(MAX) of the integrated switching MOSFET, 650 V = 1, 725 V = 2.

3. Package: D: SO-16B.

Additional Features:• Less than ±3% CC regulation over line and load• Power Factor >0.9• Ensures monotonic VA reduction with TRIAC phase angle• Low THD, 15% typical for dimmable bulbs, as low as 7% in

optimized designs

Notes: 1. Maximum practical continuous power in an open frame design

with adequate heat sinking, measured at 50˚C ambient.2. Output power scales linearly if VOUT falls in between the

specified voltages. 3. Package: SO-8 (D Package).

Additional Features:• CC regulation better than ±5%• Power factor >0.9• High efficiency >93%• Critical Conduction Mode (CrM) buck, low EMI • Excellent line noise and transient rejection
