Overview

The TPSM81299 is a synchronous boost module with 95nA ultra-low quiescent current, input current limits and fast transient response selection. The device provides a power design for portable equipment with an alkaline battery and a coin cell battery. The TPSM81299 has wide input voltage range from 0.5V to 5.5V and output voltage range from 1.8V to 5.5V. The whole family of devices has different versions for average input current limit from 5mA to 1.5A. For TPSM81299, the current limit is 1.2A. This evaluation module (EVM) is designed with 0.7V to 5.5V input voltage and the output voltage selected by jumpers, ranging from 1.8V to 5.5V.

Features
  • Input voltage range: 0.5V to 5.5V
  • 0.7V minimum input voltage for start-up
  • Input operating voltage PVIN down to 150mV with signal input AVIN > 0.7V
  • Output voltage range: 1.8V to 5.5V VSEL pin select output voltage
  • Average input current limit: 1.2A
  • 95nA typical quiescent current into VOUT
  • 60nA typical shutdown current into AVIN
  • Up to 88 % efficiency at PVIN = AVIN = 3.6V, VOUT = 5V, and IOUT = 10μA
  • Up to 94 % efficiency at PVIN = AVIN = 3.6V, VOUT = 5V, and IOUT = 200mA
  • True disconnection at EN low
  • Automatic PFM/PWM mode transition
  • Auto pass-through at AVIN > VOUT
  • Output SCP and thermal shutdown protections
  • QFN package (3mm x 2.7mm x 1.27mm)
