ZXLD1601

ADJUSTABLE DC - DC BOOST CONVERTER WITH INTERNAL SWITCH IN SC70

The ZXLD1601 is a PFM inductive boost converter designed to provide output voltages of up to 28V from a 2.5V to 5.5V input supply.

The ZXLD1601 includes the output switch and peak current sense resistor, and can provide up to 10mA output current at maximum output voltage. Higher current is available at lower output voltages.

Quiescent current is typically and a shutdown function is provided to reduce this current to less than 100nA in the ‘off’ state.

ADVANCED FEATURES
• Internal 30V NDMOS switch, current sense and
output setting resistors.

Output voltage is set to a nominal value between 26V and 28V, by an internal resistor network, but can be adjusted to lower values by external resistors, an external PWM control signal applied to the ‘Enable’ pin, or a combination of the two. Depending upon the control frequency, the PWM signal will provide either continuous low ripple or gated control. The PWM filter components are contained within the chip. Minimum output voltage is determined by the input supply.

The device is assembled in a low profile SC70-6 pin package.
