Product Overview
TPS62301 is a Texas Instruments synchronous step-down converter in the Power_Management category. The device is specified for a 2.7 V to 6 V input range and the TPS62301 option provides a fixed 1.5 V output. It supports 500 mA continuous output current at VI = 2.7 V, making it suitable for regulated low-voltage rails within the stated current range.
The converter uses 3 MHz typical switching operation, with an oscillator range of 2.65 MHz to 3.35 MHz. External clock synchronization is supported across the same 2.65 MHz to 3.35 MHz range, with a 20% to 80% synchronization-clock duty-cycle window. Power-save operation is reflected in the 86 uA typical quiescent current condition, while forced switching at no load is specified at 3.6 mA typical.
Package options include QFN-10 3 x 3 mm and CSP-8 chip-scale formats. Thermal data includes 49 °C/W and 2050 mW for the QFN-10 DRC package on a low-K board at TA <= 25 °C, and 250 °C/W and 400 mW for the CSP-8 YZD package. The operating ambient temperature range is -40 °C to 85 °C.
