76V, 300mW Boost Converter and Current
Monitor for APD Bias Applications
General Description
The MAX15059 constant-frequency pulse-width modu-
lating (PWM) step-up DC-DC converter features an
internal switch and a high-side current monitor with high-
speed adjustable current limiting. This device is capable
of generating output voltages up to 76V (300mW for
the MAX15059A and 200mW for the MAX15059B) and
provides current monitoring up to 4mA. The MAX15059
operates from 2.8V to 5.5V.
The constant-frequency (400kHz) current-mode PWM
architecture provides low-noise-output voltage that is
easy to filter. A high-voltage internal power MOSFET
allows this device to boost output voltages up to 76V.
Internal soft-start circuitry limits the input current when
the boost converter starts. The MAX15059 features a
shutdown mode to save power.
The MAX15059 includes a current monitor with more
than three decades of dynamic range and monitors
current ranging from 500nA to 4mA with high accuracy.
Resistor-adjustable current limiting protects the APD
from optical power transients. A clamp diode protects
the monitor’s output from overvoltage conditions. Other
protection features include cycle-by-cycle current limit-
ing of the boost converter switch, undervoltage lockout
(UVLO), and thermal shutdown if the die temperature
reaches +125 N C.
The MAX15059 is available in a thermally enhanced,
lead-free, 16-pin TQFN-EP package and operates over
the -40 N C to +125 N C temperature range.
