Features
Description
• 650V avalanche rugged CoolMOS™ with built-in The CoolSET™-F3 meets the requirements for Off-Line
Startup Cell
Battery Adapters and low cost SMPS for the lower power
• Active Burst Mode for lowest Standby Power
range. Adopting the BiCMOS technology, the IC can
• Fast load jump response in Active Burst Mode provide a wider VCC range up to 26V. Furthermore the
• 100kHz internally fixed switching frequency
Active Burst Mode is integrated to achieve the lowest
• Built-in latched Off Mode for Overtemperature,
Overvoltage & Short Winding Detection
Standby Power Requirements <100mW at no load and V_in
= 270VAC. As the controller is always active during the
• Auto Restart Mode for Overload, Open Loop & Active Burst Mode, it is an immediate response on load
VCC Undervoltage
jumps. And it leads to <1% ripple of the output voltage. In
• Built-in Soft Start
case of Overtemperature, Overvoltage or Short Winding,
• Built-in and extendable blanking Window for short it enters into Latched Off Mode, which can be reset by re-
duration high current
cycling the AC main line. When there are open loop and
• External latch enable function
overload conditions, it would enter Auto Restart Mode. In
• Max Duty Cycle 75%
addition, an external latch enable function is provided for
• Overall tolerance of Current Limiting < ±5%
extra flexibility in protection. With the built-in soft start, the
• Internal PWM Leading Edge Blanking
component count can be further reduced. The internal
• BiCMOS technology provide wide VCC range
precise peak current limitation can effectively optimize the
• Frequency jitter and soft driving for low EMI
dimension of the transformer and the output diode. The
built-in and extendable blanking window can prevent the
mis-triggering of Auto Restart Mode. The frequency jitter
mode can effectively reduce the EMI noise and further
reduce the components in input filter.
