ESCRIPTIO
The LT
1106 is the industry’s first DC/DC converter
designed for use on Type I and Type II PCMCIA cards. The
device senses the VPP1 and VPP2 lines at the PCMCIA
socket and generates a regulated 12V, 60mA program-
ming supply if the socket does not provide it. Internal logic
simplifies the interface to PCMCIA card microcontrollers.
One input selects a 12V or 5V regulated output, while
another input controls micropower shutdown. Two logic
outputs indicate when the selected programming voltage
is valid and whether the input supply is 3.3V or 5V.
The regulator features Burst Mode
TM
operation with a 0.5A,
300mV switch for efficiency up to 85%. High frequency
500kHz switching permits the use of small value, flat
inductors that fit neatly on PCMCIA cards. The device
requires just 1
μ
F of output capacitance.
Quiescent current is 750
μ
A which drops to 350
μ
A when
the card runs off the socket supply. The shutdown pin
reduces supply current to only 10
μ
A. The device includes
a soft start feature which limits supply current transients
when the card is inserted into a hot socket.
