DESCRIPTION (CONTINUED)
The TPS62000 is a synchronous current-mode PWM converter with integrated N- and P-channel power
MOSFET switches. Synchronous rectification is used to increase efficiency and to reduce external component
count. To achieve the highest efficiency over a wide load current range, the converter enters a power-saving
pulse-frequency modulation (PFM) mode at light load currents. Operating frequency is typically 750 kHz, allowing
the use of small inductor and capacitor values. The device can be synchronized to an external clock signal in the
range of 500 kHz to 1 MHz. For low-noise operation, the converter can be operated in the PWM mode and the
internal antiringing switch reduces noise and EMI. In the shutdown mode, the current consumption is reduced to
less than 1
μ
A. The TPS62000-HT is available in the 10-pin (HKK). The dvice operates a free-air temperature
range of –55°C to 210°C.
