Figure 5. Functional Diagram
VP Input and VL Logic Supply
An internal linear regulator supplied by VP produces
the +4.65V supply (VL) that powers the PWM controller,
logic, reference, and other blocks within the
MAX1762/MAX1791. This +4.65V low-dropout linear
regulator can supply up to 25mA for external loads.
Bypass VL to GND with at least a 1μF ceramic capaci-
tor. V VP can range between 5V and 20V. VL is turned
off when the device is in shutdown and drops by
approximately 500mV during a fault condition, such as
when the output is short circuited to ground, and recov-
ers when SHDN is cycled or power is reset. If VL is not
driven externally, then V VP should be at least 5V to
ensure operation. If V VP is running from a 5V (±10%)
supply, V VP should be externally connected to VL.
