DESCRIPTION

The TSM006 integrated circuits incorporate all circuitry to implement off line or DC-DC power supply applications using a fixed frequency current mode control.

Based on a standard current mode PWM controller, these devices include additional features for higher integration.

■ Current-mode PWM Controller

■ High-current output drive suitable for Power MOSFET

■ Automatic burst mode in zero-load condition

■ Primary overcurrent protection (hiccup mode)

■ Internal leading edge blanking on current sense

■ External slope compensation capability

■ Programmable soft start

■ Frequency modulation for low emi

■ Accurate oscillator frequency

■ 77 duty cycle limitation

■ 5V reference

■ Under voltage protection

■ Thermal shutdown at 130°C

■ 2kV ESD protection

APPLICATION

■ AC/DC adapter
