TNY178PN Offline Switcher

Description

TNY178PN features simple ON/OFF control without the need for loop compensation, a 650V rated MOSFET, selectable current limit via the BP/M pin, and built-in protection functions including auto-restart and thermal shutdown. This device is widely used in low-power switch-mode power supplies for appliances, standby converters, and auxiliary power applications.

TinySwitch-LTcombines a high voltage power MOSFET switch with a power supply controller in one device. Unlike conventional PWM (pulse width modulator) controllers, it uses a simple ON/OFF control to regulate the output voltage. The controller consists of an oscillator, enable circuit (sense and logic), current limit state machine, 5.85 V regulator, BYPASS/MULTI-FUNCTION pin undervoltage, overvoltage circuit, and current limit selection circuitry, over- temperature protection, current limit circuit, leading edge blanking, and a 700 V power MOSFET. TinySwitch-LTincorporates additional circuitry for auto-restart, adaptive switching cycle on-time extension, and frequency jitter. Figure 2 shows the functional block diagram with the most important features.

Design Notes

  • UART interface allows straightforward integration with microcontrollers (e.g., MCU, Arduino)
  • AD key mode enables standalone operation using resistor ladder inputs
  • Ensure proper power supply decoupling to avoid audio noise
  • Speaker outputs can directly drive small speakers (typically 8Ω)
  • File naming and folder structure on microSD must follow module requirements
  • Use FAT16/FAT32 formatted microSD cards for compatibility

How to Choose This Part

  • Select for simple audio playback without complex DSP requirements
  • Ideal for low-cost designs requiring serial control
  • Ensure compatibility with system voltage and UART logic levels
  • Evaluate need for onboard amplification vs external audio stages
  • Consider storage capacity requirements of microSD card
