Note 3: Minimum and maximum limits tested with ST1, ST2 unconnected.
Note 4: Total driver resistance includes the on-resistance of the top and the bottom internal FETs. If R OH is the high-side resistance,
and R OL is the low-side resistance, R OHL = R OH + R OL .

FUNCTION
Clock Input/Oscillator Frequency Adjust. When MODE is HIGH, set the internal oscillator frequency by
connecting a 10k ? or greater resistor from CK_RS to ground. When MODE is LOW, apply an external
clock signal to CK_RS. The MAX256 outputs switch at one half the external clock frequency.
V CC Supply Voltage, +3.0V ≤ V CC ≤ +5.5V.
Bypass V CC to ground with a 4.7μF capacitor and a 470nF ceramic capacitor.
Mode Control Input. Drive MODE high to enable internal oscillator. Drive MODE low and supply a valid
clock signal on CK_RS for external clock mode.

Transformer Drive Output 1
EP is internally connected to GND. Connect to a large ground plane to maximize thermal
performance; not intended as an electrical connection point.
