Description

The 1200AP100 is PWM Current-Mode Controller for Universal Off-Line Supplies Featuring Low Standby Power.

Housed in SOIC−8 or PDIP−8 package, the NCP1200A enhances the previous NCP1200 series by offering a reduced optocoupler current together with an increased drive capability. Due to its novel concept, the circuit allows the implementation of complete off−line AC−DC adapters, battery charger or a SMPS where standby power is a key parameter.

With an internal structure operating at a fixed 40 kHz, 60 kHz or 100 kHz, the controller supplies itself from the high−voltage rail, avoiding the need of an auxiliary winding. This feature naturally eases the designer task in battery charger applications. Finally, current−mode control provides an excellent audio−susceptibility and inherent pulse−by−pulse control.

A PWM (Pulse-Width Modulation) Current-Mode Controller is a type of electronic control circuit used in power electronics and voltage regulation. This controller is commonly used in switch-mode power supplies, such as buck, boost, and buck-boost converters. It is designed to regulate the current flowing through an inductor or load by adjusting the width of the output pulses.

Features

• Pb−Free Packages are Available

• No Auxiliary Winding Operation

• Auto−Recovery Internal Output Short−Circuit Protection

• Extremely Low No−Load Standby Power

• Current−Mode Control with Skip−Cycle Capability

• Internal Temperature Shutdown

• Internal Leading Edge Blanking

• 250 mA Peak Current Capability

Description

K13A25D is Silicon N-Channel MOSFET(Metal Oxide Semiconductor Field Effect Transistor). This is a type of field effect transistor (FET) that uses an N-type semiconductor material as the conducting channel to control the flow of current.

Features

(1) Low drain-source on-resistance: RDS(ON) = 0.19 Ω (typ.)

(2) Low leakage current: IDSS = 10 µA (max) (VDS = 250 V)

(3) Enhancement mode: Vth = 1.5 to 3.5 V (VDS = 10 V, ID = 1 mA)

Absolute Maximum Ratings (Ta = 25°C)

1. Drain to source voltage: VDSS = 250 V

2. Gate to source voltage: VGSS = ± 20 V

3. Drain current: ID = 13 A

4. Power Dissipation: Pd = 35 W

5. Channel temperature: Tch = 150 °C

6. Storage temperature: Tstg = -55 to +150 °C

 

Applications:

• Switching Voltage Regulators
