DO1608-103 Overview

2 ELEMENT, 10 uH, GENERAL PURPOSE INDUCTOR, SMD

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. 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 TSOT23-5
pin package.
ADVANCED FEATURES
Internal 30V NDMOS switch
True analog output voltage control via PWM
with internal filter
