Internal Oscillator
The internal oscillator generates a clock with the fre-
quency proportional to the inverse of R T . The oscillator
frequency is adjustable from 125kHz to 1.5MHz with
better than 8% accuracy using a single resistor con-
nected from RT/SYNC to SGND (MAX5060) and from
RT/SYNC/EN to SGND (MAX5061). The frequency accu-
racy avoids the over-design, size, and cost of passive
filter components like inductors and capacitors. Use the
following equation to calculate the oscillator frequency:
for 120k ? ≤ R T ≤ 500k ? :
The oscillator also generates a 2V P-P voltage-ramp sig-
nal for the PWM comparator and a 180° out-of-phase
clock signal for CLKOUT (MAX5060) to drive a second
DC-DC converter out-of-phase.
Synchronization
The MAX5060/MAX5061 can be easily synchronized by
connecting an external clock to RT/SYNC (MAX5060) or
RT/SYNC/EN (MAX5061). If an external clock is pre-
sent, then the internal oscillator is disabled and the
external clock is used to run the MAX5060/MAX5061. If
the external clock is removed, the absence of clock for
R T =
for 40k ? ≤ R T ≤ 120k ? :
R T =
6 . 25 × 10 10
f SW
6 . 40 × 10 10
f SW
32μs is detected and the circuit starts switching from
the internal oscillator. Pulling RT/SYNC on the MAX5060
or RT/SYNC/EN on the MAX5061 to ground for at least
50μs disables the converter.
Use an open-collector transistor to synchronize the
MAX5060/MAX5061 with the external system clock (see
Figures 1 and 2).
