Brief Description
The KTB851 is a high efficiency step down
converter, using constant frequency PWM current
mode control. It uses 1.6MHz high switching
frequency which allows the use of small external
components. The 2.7V to 5.5V input operating range
is ideal for Li-Ion/Polymer powered devices and
systems running from regulated 3.3V or 5V voltage
rails. 100 duty cycle operation provides the
greatest design flexibility for achieving the lowest
dropout.
Low output voltage down to 0.6V can be achieved
due to the KTB851’s low internal voltage reference.
The KTB851 is designed to maintain high efficiency
throughout the operating range, which is critical for
portable applications. In addition, the KTB851 has an
option for output auto discharge feature. This
enables the device to quickly discharge the output
when the device is disabled.
The KTB851 is available in a small 5-pin TSOT23,
6-pin TDFN 1.6 x 1.6 x 0.75mm and 6-pin UTDFN
1.6 x 1.6 x 0.55mm package.
