FUNCTION
Power Ground for DC-DC1 and DC-DC2
DC-DC2 Converter Switching Node. Connect an LC filter to LX2. Use a capacitor with a maximum
ESR of 0.3 I .
Battery Supply-Voltage Input. V INB supplies power to DC-DC2 and DC-DC3.
Bootstrap Capacitor Connection for DC-DC2. Connect a 0.1 F F capacitor from BST2 to LX2.
Bootstrap Capacitor Connection for DC-DC3. Connect a 0.1 F F capacitor from BST3 to LX3.
DC-DC3 Converter Switching Node. Connect an LC filter to LX3. Use a capacitor with a maximum
ESR of 0.3 I .
Power Ground for DC-DC3
DC-DC3 Feedback Input. Connect FB3 to GND for a fixed 3.3V output. Connect to a resistive
divider to adjust the output voltage between 1.22V and 8V.
DC-DC3 Converter Output
Undervoltage Switch. This switch connects the undervoltage resistor-divider to ground during
normal operation. When only DC-DC1 is running, this switch is open to reduce current consumption,
and the undervoltage circuit is not active.
Undervoltage Lockout Sense Input. Connect a resistor-divider between the battery, UVI, and UVS to
set the undervoltage lockout level. The nominal threshold for UVI is 1.205V.
DC-DC3 Converter Enable Input. Drive EN3 high to enable the DC-DC3 converter. Drive low to
disable the DC-DC3 converter.
DC-DC2 Converter Enable Input. Drive EN2 high to enable the DC-DC2 converter. Drive low to
disable the DC-DC2 converter.
Active-Low Open-Drain Overtemperature Output. OT output low indicates that all converters except
DC-DC1 are in shutdown due to an overtemperature condition.
Active-Low Open-Drain Undervoltage Output. UVO asserts low when the voltage at UVI falls below
1.205V Q 2%. The UVO output is high impedance when only DC-DC1 is operating (standby mode).
DC-DC Converters Synchronization Input. For MAX16920A, the SYNC frequency is divided by 2,
whereas for the MAX16920B the switching frequency is same as the SYNC frequency. Connect
SYNC to GND if SYNC is not used. The SYNC input is a Schmitt trigger type to accommodate a
lowpass-filtered square-wave input. The duty-cycle range of the signal is 30% to 70%. The SYNC
input has an internal 200k I pulldown resistor.
DC-DC3 Open-Drain Power-Good Output. PG3 goes low when OUT3 is out of
regulation. In standby mode, PG3 is high-impedance.
DC-DC2 Open-Drain Power-Good Output. PG2 goes low when OUT2 is out of
regulation. In standby mode, PG2 is high-impedance.
Linear Regulator Open-Drain Power-Good Output. PGA goes low when LDO is out of regulation. In
standby mode, PGA is high-impedance.
Active-Low Open-Drain Reset Output from DC-DC1. POR is low when DC-DC1 is out of regulation and
has a delay time of 7.5ms to 8ms in the MAX16920B (2MHz) and 5.1ms in the MAX16920A (400kHz).
Exposed Pad. Connect the exposed pad to ground.
