Product Highlights
Features Optimized for Lowest System Cost
Fully integrated auto-restart for short-circuit and open
loop protection
Self-biased supply – saves transformer auxiliary winding
and associated bias supply components
Tight tolerances and negligible temperature variation on
key parameters eases design and lowers cost
High maximum switching frequency allows very low
ux density transformer designs, practically eliminating
audible noise
Frequency jittering greatly reduces EMI
Packages with large creepage to high voltage pin
Lowest component count switcher solution
Much Better Performance over Linear/RCC
Lower system cost than RCC, discrete PWM and other
integrated solutions
Universal input range allows worldwide operation
Simple ON/OFF control – no loop compensation needed
No bias winding – simpler, lower cost transformer
High frequency switching – smaller and lower cost
transformer
Very low component count – higher reliability and single
side printed circuit board
High bandwidth provides fast turn on with no overshoot
and excellent transient load response
Current limit operation rejects line frequency ripple
Built-in current limit and hysteretic thermal shutdown
protection
EcoSmart

Notes: 1. Typical continuous power in a non-ventilated
enclosed adapter measured at 50 °C ambient. 2. Maximum practical
continuous power in an open frame design with adequate heat
sinking, measured at 50 °C ambient. 3. Packages: P: DIP-8B,
G: SMD-8B. For lead-free package options, see Part Ordering
Information. 4. For designs without a Y capacitor, the available power
may be lower (see Key Applications Considerations).
source, frequency jittering, cycle-by-cycle current limit, and
thermal shutdown circuitry onto a monolithic IC. The start-up
and operating power are derived directly from the DRAIN pin,
eliminating the need for a bias winding and associated circuitry.
The 200 kHz maximum switching frequency allows very
low ux transformer designs, practically eliminating audible
noise with the simple ON/OFF control scheme using standard
varnished transformer construction. Efcient operation at this
high switching frequency is achieved due to the optimized
switchingcharacteristicsandsmallcapacitancesoftheintegrated
power MOSFET.The fully integrated auto-restart circuit safely
limits output power during fault conditions such as output short
circuit or open loop, reducing component count and secondary
feedback circuitry cost. The internal oscillator frequency is
jittered to signicantly reduce both the quasi-peak and average
EMI, minimizing ltering cost.
