PT1305
High Voltage Step-Up Converter
GENERAL DESCRIPTION
The PT1305 is a step-up DC/DC converter designed for
driving up to 24V from a single cell Lithium Ion battery.
The PT1305 switches at 1.25MHz, allowing the use of
tiny, low cost and low height inductors and capacitors.
A constant frequency internally compensated current
mode PWM architecture results in low, predictable
output noise that is easy to filter. Low ESR ceramic
capacitors can be used at the output, further reducing
noise to millivolt level. The high voltage switch on the
PT1305 is rated at 26V, making the devices ideal for
boost converters up 24V. It can generate 18V at 30mA
from 3.6V supply. The PT1305 is available in SOT23-5
and SOT23-6 packages.
