The LTC1314/LTC1315 provide 0V, 3.3V, 5V, 12V and
Hi-Z power output for flash VPP programming. A built-in
charge pump produces 12V of gate drive for inexpensive
N-channel 3.3V/5V VCC switching. The 12V regulator can
be shut down when 12V is not required at VPPOUT. All
digital inputs are TTL compatible and interface directly
with industry standard PC card interface controllers.

APPLICATIONS INFORMATION
cally rated with an absolute maximum of 13.5V and VPP
must be maintained at 12V ±5% under all possible load
conditionsduringeraseandprogramcycles. Undervoltage
can decrease specified flash memory reliability and over-
voltage can damage the device.
PCMCIA VPP control is easily accomplished using the
LTC1314 or LTC1315 switching matrix. Two control bits
(LTC1314) or four control bits (LTC1315) determine the
outputvoltageandstandby/operatemodeconditions. Out-
put voltages of 0V, VCCIN (3.3V or 5V), VPPIN, or a high
impedancestateareavailable. Wheneitherthehighimped-
anceorlowvoltage(0V)conditionsareselected,thedevice
switches into “sleep” mode and draws 0.1µA of current
from the VDD supply.
VCC Switch Driver and VPP Switch Matrix
Figures 1 and 2 show the approach that is very space and
power efficient. The LTC1314/LTC1315 used in conjunc-
tion with the LT1301 DC/DC converter, provide complete
power management for a PCMCIA card slot. The LTC1314/
LTC1315 and LT1301 combination provides a highly effi-
cient, minimal parts count solution. These circuits are
especially good for applications that are adding a PCMCIA
socket to existing systems that currently have only 5V or
3.3V available.
The LTC1314/LTC1315 are low resistance power MOSFET
switchingmatricesthatoperatefromthecomputersystem
main power supply. Device power is obtained from VDD,
which is 5V ±0.5V. The gate drives for the NFETs (both
internal and external) are derived from internal charge
pumps,thereforeVPPIN isonlyrequiredwhenit’sswitched
to VPPOUT. Internal break-before-make switches deter-
mine the output voltage and device mode.
The LTC1314 drives three N-channel (LTC1315 six
N-channel) MOSFETs that provide VCC pin power switch-
ing. On-chip charge pumps provide the necessary voltage
to fully enhance the switches. With the charge pumps on-
chip, the MOSFET drive is available without the need for a
12V supply. The LTC1314/LTC1315 provide a natural
break-before-make action and smooth transitions due to
Flash Memory Card VPP Power Considerations
PCMCIA compatible flash memory cards require tight
regulation of the 12V VPP programming supply to ensure
that the internal flash memory circuits are never subjected
to damaging conditions. Flash memory circuits are typi-

APPLICATIONS INFORMATION
the asymmetrical turn-on and turn-off of the MOSFETs.
The LT1301 switching regulator is in shutdown mode and
consumes only 10µA until the VPP pins require 12V.
With Higher Voltage Supplies Available
Often systems have an available supply voltage greater
than 12V. The LTC1314/LTC1315 can be used in conjunc-
tion with an LT1121 linear regulator to supply the PC card
socket with all necessary voltages. Figures 3 and 4 show
these circuits. The LTC1314/LTC1315 enable the LT1121
linear regulator only when 12V is required at the VPP pins.
In all other modes the LT1121 is in shutdown mode and
consumes only 16µA. The LT1121 also provides thermal
shutdown and current limiting features to protect the
socket, the card and the system regulator.
The VPP switching is accomplished by a combination of
the LTC1314/LTC1315 and LT1301. The LT1301 is in
shutdown mode to conserve power until the VPP pins
require 12V. When the VPP pins require 12V, the LT1301
isactivatedandtheLTC1314/LTC1315’sinternalswitches
route the VPPIN pin to the VPPOUT pin. The LT1301 is
capable of delivering 12V at 120mA maintaining high
efficiency. The LTC1314/LTC1315’s break-before-make
andslope-controlledswitchingwillensurethattheoutput
voltage transition will be smooth, of moderate slope, and
without overshoot. This is critical for flash memory prod-
ucts to prevent damaging parts from overshoot and
ringing exceeding the 13.5V device limit.
Supply Bypassing
For best results, bypass VCCIN and VPPIN at their inputs
with1µFcapacitors. VPPOUT shouldhavea0.01µFto0.1µF
capacitor for noise reduction and electrostatic discharge
(ESD) damage prevention. Larger values of output capaci-
tor will create large current spikes during transitions,
requiring larger bypass capacitors on the VCCIN and VPPIN
pins.
