SLP
low. When
SLP
is high,
the switching step-down converters are active. The output
voltage of the sleep LDOs is set to be the same as the
switching step-down converters as described in the
Setting the Output Voltages
section. SLPIN is the input to
the V1 and V2 sleep LDOs and must connect to IN.
V3 (VCC_CORE) Step-Down
DC-DC Converter
V3 is a 1MHz current-mode step-down converter that
supplies loads up to 500mA. The V3 output voltage is set
by the I
2
C serial interface to between 0.7V and 1.475V in
25mV increments. The default voltage on power-up is
1.3V. See the
Serial Interface
section for details.
Forced PWM on REG3
Under moderate to heavy loading, the V3 always operates
in a low-noise PWM mode with constant frequency and
modulated pulse width. Switching harmonics generated by
fixed-frequency operation are consistent and easily filtered.
With light loads (<30mA) and PWM3 low, V3 operates
in an enhanced-efficiency Idle Mode during which the
converter switches only as needed to service the load.
With PWM3 high, V3 operates in low-noise forced-PWM
mode under all load conditions.
Linear Regulators (V4, V5, and V6)
V4 (VCC_PLL)
V4 is a linear regulator that provides a fixed 1.3V output
and supplies loads up to 35mA. The power input for the
V4 and V5 linear regulators is IN45, which is typically
connected to V2. To enable V4 on the MAX1587, drive
ON4 high, or drive ON4 low for shutdown. On the
MAX1586, the enable pins for V4 and V5 are combined.
Drive ON45 high to enable V4 and V5, or drive ON45 low
for shutdown. V4 is intended to connect to VCC_PLL.
V5 (VCC_SRAM)
V5 is a linear regulator that provides a fixed 1.1V output
and supplies loads up to 35mA. The power input for the
V4 and V5 linear regulators is IN45, which is typically
connected to V2. To enable V5 on the MAX1587, drive
ON5 high, or drive ON5 low for shutdown. On the
MAX1586, the enable pins for V4 and V5 are combined.
Drive ON45 high to enable V4 and V5, or drive ON45 low
for shutdown. V5 is intended to connect to VCC_SRAM.
V6 (VCC_USIM—MAX1586 Only)
V6 is a linear regulator on the MAX1586 that supplies
loads up to 35mA. The V6 output voltage is pro-
grammed with the I
2
C serial interface to 0V, 1.8V, 2.5V,
or 3.0V. The power-up default for V6 is 0V. See the
Serial Interface
section for details on changing the volt-
age. The power input for the V6 linear regulator is IN6,
which is typically connected to V1. To enable V6, drive
ON6 high, or drive ON6 low for shutdown. V6 is intend-
ed to connect to VCC_USIM.
V7 Always-On Output (VCC_BATT)
The V7 output is always active if V1 is enabled and in
regulation or if backup power is present. When ON1 is
high and V1 is in regulation, V7 is sourced from V1 by
an internal MOSFET switch. When ON1 is low or V1 is
