The TNY276PN uses on\/off control to provide a flexible design solution and achieve lower system costs and a wider output power range. Integrates a 700 V power MOSFET, oscillator, high voltage switching current source, current limiting (user optional) and thermal shutoff circuit.
TNY276PN Features
? Strict I2f parameter tolerances reduce system costs
- Efficient use of MOSFETs and magnetic core materials for power output
- Reduces the maximum overload power, thereby reducing the cost of transformers, primary clamping and secondary components
? Extended on-time - Stability\/maintenance time of the output at lower input voltages can be maintained by using lower capacity input electrolytic capacitors
? Self-bias: No bias winding or bias element required
? Frequency jitter reduces EMI filtering costs
? The pin layout simplifies the design of cooling copper placement on the PCB board
? The source pin is a quiet point on the \"electrical\
? Simple on\/off control without loop compensation
? Different current limiting points can be selected by the BP\/M pin capacitance value
- Higher current limiting points lead to higher peak power, or higher continuous output power in open applications
- Lower current limiting points increase the efficiency of enclosed adapter\/charger designs
- Allows interchangeability between adjacent TinySwitch-III series products without the need to redesign the circuit
