ZXLD1615 - ADJUSTABLE DC-DC BOOST CONVERTER

Description

The ZXLD1615 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 ZXLD1615 includes the output switch and peak current sense resistor, and can provide up to 10mA output current at maximum output voltage.

Features

  • Internal 30V NDMOS switch.
  • True analog output voltage control via PWM with internal filter.

ZXLD1615 ADJUSTABLE DC-DC BOOST CONVERTER WITH INTERNAL SWITCH IN TSOT23-5 DESCRIPTION The ZXLD1615 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 ZXLD1615 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 60␮A and a shutdown function is provided to reduce this current to less than 100nA in the 'off' state. Nominal output voltage can be set up to a maximum of 28V by two external resistors and can be adjusted to lower values by a PWM control signal applied to the 'Enable' pin.
