Internal-Switch Boost Regulator with Integrated
7-Channel Scan Driver, Op Amp, and LDO
If the gate-shading control is enabled, a gate-shading
period is initiated by a falling edge of a CK_ input when-
ever V DTS is less than 100mV. Once the gate-shading
period is initiated, a switch across C SET (S DTS ) opens,
allowing C SET to be charged through R SET . Once V DTS
reaches 1.24V, S DTS closes to discharge C SET , the
gate-shading period is terminated, and the CKH_ output
states are directly determined by their corresponding
CK_ input logic states again. Once a gate-shading
period is initiated, V DTS must charge to 1.24V and sub-
sequently discharge back below 100mV, before the next
CK_ falling can activate a new gate-shading period.
By configuring R SET and C SET as shown in Figure 1, the
gate-shading period time duration is determined by R SET
and C SET and V LDOO (see the Setting the Gate-Shading
Period Time Duration section). The gate-shading control
can be disabled by removing R SET . If R SET is removed,

the states of the CKH_ outputs are always determined by
their corresponding CK_ input logic states. See Figure 5.
Low-Dropout Linear Regulator (LDO)
The MAX17117 has an integrated 0.8 I pass element
and can provide at least 350mA. The output voltage is
accurate within Q 1%.
Thermal-Overload Protection
When the junction temperature exceeds T J = +170 N C
(typ), a thermal sensor activates a fault-protection latch,
which shuts down all outputs, allowing the IC to cool
down. All outputs remain off until the IC cools and the
input voltage is cycled below, then back above the IN
UVLO threshold.
The thermal-overload protection protects the IC in the
event of fault conditions. For continuous operation, do
not exceed the absolute maximum junction temperature
rating of T J = +150 N C.
