DPA422PN
The DPA-Switch? IC family is a highly integrated solution for
DC-DC conversion applications with 16-75 VDC input.
DPA-Switch uses the same proven topology as TOPSwitch?,
cost effectively integrating a power MOSFET, PWM control, fault
protection and other control circuitry onto a single CMOS chip.
High performance features are enabled with three user
configurable pins. Hysteretic thermal shutdown is also provided.
In addition, all critical parameters (i.e. current limit, frequency,
PWM gain) have tight temperature and absolute tolerance, to
simplify design and reduce system cost.
LNK306PN IC – Power Integrations – AC-DC Off Line Switcher IC
The LNK306PN is specifically designed to replace all linear and capacitor-fed (cap dropper) non-isolated power supplies in the under 360 mA output current range at equal system cost while offering much higher performance and energy efficiency. LinkSwitch-TN devices integrate a 700 V power MOSFET, oscillator, simple On/Off control scheme, a high-voltage switched current source, frequency jittering, cycle-by-cycle current limit Figure 1. Typical Buck Converter Application (See Application Examples Section ? ?for Other Circuit Configurations).and thermal shutdown circuitry onto a monolithic IC. The start-up and operating power are derived directly from the voltage on the DRAIN pin, eliminating the need for a bias supply and associated circuitry in buck or fly back converters. The fully integrated auto-restart circuit in the LNK306 safely limits output power during fault conditions such as short-circuit or open loop, reducing component count and system-level load protection cost. ?A local supply provided by the IC allows use of a non-safety graded optocoupler acting as a level shifter to further enhance line and load regulation performance in buck and buck-boost converters.
LNK420EG IC – Power Integrations – LED Driver Off Line Switcher IC
The LNK420EG dramatically simplifies implementation of LED drivers requiring long lifetime, high efficiency, PF >0.9, and TRIAC dimming capability(LNK403-410). The single-stage combined power factor and constant-current controller eliminates a switching stage and the electrolytic bulk capacitor. ?The advanced primary-side control used by the?LNK420EG?device provides accurate constant current control while eliminating the need for an optocoupler and current sensing circuits.LinkSwitch-PH incorporates a 725 V power FET, a continuous-mode PWM controller, a high-voltage switched current source for self biasing, frequency jittering, protection circuitry including cycle-by-cycle current limit and hysteretic thermal shutdown.
TOP227YN IC – Power Integrations – Off Line Switcher IC
TOP227YN belongs to TOPSwitch-II Family from the manufacturer "Power Integration". It is three-Terminal Off-Line PWM Switch. Description The second generation TOPSwitch?-II family is more cost effective and provides several enhancements over the first generation TOPSwitch family. The TOPSwitch-II family extends the power range from 100W to 150W for 100/115/ 230 VAC input and from 50W to 90W for 85-265 VAC universal input. This brings TOPSwitch technology advantages to many new applications, i.e. TV, Monitor, Audio amplifiers, etc. Many significant circuit enhancements that reduce the sensitivity to board layout and line transients now make the design even easier. The standard 8L PDIP package option ?reduces cost in lower power, high efficiency applications. The internal lead frame of this package uses six of its pins to transfer heat from the chip directly to the board, eliminating the cost of a heat sink. TOPSwitch incorporates all functions necessary for a switched mode control system into a three terminal monolithic IC: power MOSFET, PWM controller, high voltage start up circuit, loop compensation and fault protection circuitry.
TOP247YN IC – Power Integrations – Off Line Switcher IC
TOP247YN belongs to TOPSwitch-GX Family from the manufacturer "Power Integrations". It is with Extended Power, Design Flexiblity, EcoSmart & Integrated Off-line Switcher. TOPSwitch-GX uses the same proven topology as TOPSwitch, cost effectively integrating the high voltage power MOSFET, PWM control, fault protection and other control circuitry onto a single CMOS chip. Many new functions are integrated to reduce system cost and improve design flexibility, performance and energy efficiency. Depending on package type, either 1 or 3 additional pins over the TOPSwitch standard DRAIN, SOURCE and CONTROL terminals allow the following functions: line sensing (OV/UV, line feed-forward/DCMAX reduction), accurate externally set current limit, remote ON/OFF, synchronization to an external lower frequency, and frequency selection (132 kHz/66 kHz). All package types provide the following transparent features: Soft-start, 132 kHz switching frequency (automatically reduced at light load), frequency jittering for lower EMI, wider DCMAX, hysteretic thermal shutdown, and larger creepage packages. In addition, all critical parameters (i.e. current limit, frequency, PWM gain) have tighter temperature and absolute tolerances to simplify design and optimize system cost.
