ZXLD1601
ADJUSTABLE DC - DC BOOST CONVERTER WITH INTERNAL SWITCH IN SC70
DESCRIPTION
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 60A and a shutdown function is provided to reduce this current to less than 100nA in the ‘off’ state. 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.
