TPS60400DBVR TI DC-DC Switching Regulators

The TPS60400DBVR is a charge pump voltage inverter from Texas Instruments, generating an unregulated negative output from a positive input ranging from 1.6 V to 5.5 V, using only three small 1‑µF ceramic capacitors . Verify input voltage between 1.6 V and 5.5 V, confirm maximum output current ≤60 mA, note typical quiescent current of 65 µA and 90% conversion efficiency . The device features a variable switching frequency (50 kHz to 250 kHz) with PowerSave mode for improved efficiency at light loads, plus an integrated active Schottky diode for startup into load . Operating temperature range is -40 °C to +85 °C . Housed in a 5‑pin SOT‑23 package, it is ideal for generating negative rails in LCD bias, GaAs bias for RF power amplifiers, sensor supplies in portable instruments, bipolar amplifier supplies, medical instruments, and battery‑operated equipment .
