TEA1207T is a fully integrated DC/DC converter from Philips Semiconductors. It supports up-or-down conversion, starting voltage is 1.85V, adjustable output voltage, high efficiency, low quiescent power consumption, synchronize with external clock, lithium ion battery compatibility, 100% duty cycle in down mode, undervoltage lockout, shut-down function, etc.
The Philips TEA1207T is a fully integrated DC/DC converter circuit designed for high efficiency over a large load range. It supports both up-conversion and down-conversion modes, featuring a switching frequency of 275 kHz and the ability to start up from a low input voltage of 1.85 V. The device utilizes a novel digitally controlled concept with Pulse Width Modulation (PWM) or Pulse Frequency Modulation (PFM) and fully synchronous rectification to achieve efficient power conversion.
