Product Overview
TPS62302 is a Texas Instruments synchronous step-down converter in the Power_Management category. The TPS62302 fixed-output version provides a 1.6 V output, supports up to 500 mA output current at VI = 2.7 V, and operates from a recommended 2.7 V to 6 V input range.
The converter uses 3 MHz fixed switching during normal operation, with an internal oscillator specified from 2.65 MHz to 3.35 MHz. It can synchronize to an external clock over the same 2.65 MHz to 3.35 MHz range, with a 20% to 80% external clock duty-cycle requirement. Power-save operation, PWM mode, enable control, and MODE/SYNC logic thresholds are specified in the datasheet.
Package options are QFN-10 3 x 3 mm DRC and CSP-8 YZD chip-scale package. Thermal data includes 49 °C/W junction-to-ambient resistance for DRC and 250 °C/W for YZD on low-K boards, with corresponding package power ratings and derating factors.
