    12V, 30mA Flash Memory
    Programming Supply U DESCRIPTIO FEATURES






    ■ Regulated 12V ±5% Output Voltage
    No Inductors
    Supply Voltage Range: 4.75V to 5.5V
    Guaranteed 30mA Output
    Low Power: ICC = 500µA
    ICC in Shutdown: 0.5µA
    8-Pin PDIP or SO-8 Package The LTC®1262 is a regulated 12V, 30mA output DC/DC
    converter. It is designed to provide the 12V ±5% output
    necessary to program byte-wide flash memories. The
    output will provide up to 30mA from input voltages as low
    as 4.75V without using any inductors. Only four external
    capacitors are required to complete an extremely small
    surface mountable circuit.
    The TTL compatible shutdown pin can be directly connected to a microprocessor and reduces the supply current to less than 0.5µA. The LTC1262 offers improved ...

    Linear Technology Magazine Circuit Collection, Volume II
    Application Note 66 is a compendium of "power circuits" from the first five years of Linear Technology. This application note contains circuits that can power most any system you can imagine, from desktop computer systems to micropower systems for portable and handheld equipment. Also included here are circuits that provide 300W or more of power factor corrected DC from a universal input. Battery chargers are included, some that charge several battery types, some that are optimized to charge a single type. MOSFET drivers, high side switches and H-bridge driver circuits are also included, as is an article on simple thermal analysis.

    INTRODUCTION
    Application Note 66 is a compendium of “power circuits”
    from the first five years of Linear Technology. The objective
    is to collect the useful circuits from the magazine into
    several applications notes (another, AN67, will collect
    signal processing circuits into one Application Note) so
    that valuable “gems” will not be lost. This Application Note
    contains circuits that can power most any system you can
    imagine, from desktop computer systems to micropower
    systems for portable and handheld equipment. Also included here are circuits that provide 300W or more of
    power factor corrected DC from a universal input. Battery
    chargers are included, some that charge several battery
    types, some that are optimized to charge a single type.
    MOSFET drivers, high side switches and H-bridge driver
    circuits are also included, as is an article on simple thermal
    analysis. With these introductory remarks, I’ll stand aside
    and let the authors describe their circuits. ARTICLE INDEX
