UC2843BD101 datasheet

 

Description

The UC2843BD101, UC384xB family of control ICs provides the necessary features to implement off-line or DC to DC fixed frequency current mode control schemes with a minimal external parts count. Internally implemented circuits include a trimmed oscillator for precise DUTY CYCLE CONTROL under voltage lock out featuring start-up current less than 0.5mA, a precision reference trimmed for accuracy at the error amp input, logic to insure latched operation, a PWM comparator which also provides current limit control, and a totem pole output stage designed to source or sink high peak current. The output stage, suitable for driving N-Channel MOSFETs, is low in the off state.

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.
