KA3842A datasheet

Obsolete as of 14-Sep-2013

Description

The KA3842A / KA3842AC / KA3842AE are fixed PWM controller for Off Line and DC to DC converter applications. The internal circuits include UVLO, low start up current circuit, temperature compensated reference, high gain error amplifier, current sensing comparator, and high current totem pole output for driving a POWER MOSFET. Also KA3842AC / KA3842AE provides low start up current below 0.3mA and short shutdown delay time typ. 100ns. The KA3842AC / KA3842AE has UVLO threshold of 16V(on) and 10V(off). The KA3842AC/KA3842AE can operate within 100% duty cycle.

EA1530AT SMPS controller

 

Description

The GreenChip II is the second generation of green Switched Mode Power Supply (SMPS) controller ICs. Its high level of integration allows the design of a cost effective power supply with a very low number of external components.

The TEA1530(A) (TEA1530T, TEA1530AT and TEA1530AP) can be used in fixed frequency converter designs for low voltage, high current applications. At low power (standby) levels, the system operates in cycle skipping mode which minimizes the switching losses during standby.

Features

1. Safe restart mode for system fault conditions.
2. Undervoltage protection (foldback during overload).
3. IC OverTemperature Protection (OTP) (latched).
4. Low and adjustable OverCurrent Protection (OCP) trip level.
