TEA152x:SMPS ICs for low-power systems

The TEA152x family STARplug is a Switched Mode Power Supply (SMPS) controller IC that operates directly from the rectified universal mains. It is implemented in the high-voltage EZ-HV SOI process, combined with a low-voltage Bipolar Complementary Metal-Oxide Semiconductor (BiCMOS) process. The device includes a high-voltage power switch and a circuit for start-up directly from the rectified mains voltage.A dedicated circuit for valley switching is built in, which makes a very efficient slim-line electronic power-plug concept possible.

In its most basic version of application, the TEA152x family acts as a voltage source.Here, no additional secondary electronics are required. A combined voltage and current source can be realized with minimum costs for external components. Implementation of the TEA152x family renders an efficient and low cost power supply system.

STARplug Mini演示板

The STARplug Mini Switched Mode Power Supply (SMPS) demo board comes in two versions: a 5 V version and 12 V version. The circuit implemented on this board is typically suited to low-power adapter applications.

The board has a universal mains input. The total nominal output power is rated at 3 W for the 5 V version and 5 W for the 12 V version. The flyback circuit is built around the NXP Semiconductors TEA1521T or TEA1522T STARplug IC. The STARplug Mini demo board allows customization of the input filtering, snubber circuit, regulation feedback scheme etc. Small changes in output voltage (up to 20 %) are also supported. If an alternative transformer is considered, the Printed-Circuit Board (PCB) can generate virtually any output voltage. These features make the STARplug Mini demo board a highly versatile and reliable starting point for developing custom low-power boards.

This versatility comes at the cost of PCB space, so the board is not a showcase for minimal PCB space usage and cannot be looked upon as an end-solution. However, it is very useful for exploring the STARplug family of IC’s features and functionality during development of a low-power SMPS final solution.

圖1. STARplug Mini演示板主要特性:

• Universal mains input

• Isolated output

• 5 V/3 W and 12 V/5 W version available as default configurations

• Stable regulated voltage

• Highly flexible and easily tuned to meet user requirements

• Used with the TEA1520T, TEA1521T and TEA1522T devices (SO14 package)

• Highly efficient: 5 V version > 68 %, 12 V version > 79 %

• Low standby (no-load) power: < 80 mW

• OverPower Protection (OPP)

• OverTemperature Protection (OTP)

• Built-in basic differential mode ElectroMagnetic Interference (EMI) filter.
