PRODUCTION DATA
An internal oscillator generates a 225-kHz to 1.5-MHz clock for PWM switching with 16 discrete programmable options. The switching frequency is selectable by pin-strapping through the resistor divider of MSEL1 (8 options), PMBus programming (16 options), or both, using the (33h) FREQUENCY_SWITCH command, listed in Table 7-2.
